fix(lint): make Vale prefilter portable via the plugin

skill-audit/agent-audit's Step 1 resolved vale-wrap.sh/.vale.ini via
`git rev-parse --show-toplevel`, which returns whichever repo the skill
happens to run in. Inside ai-development that works; in any external repo
that installs kyberforge@holocron as a plugin, it resolves to that repo's
own root, which has no .vale.ini — the prefilter silently fell back to
full LLM judgment. ADR-0013 named this as a deliberately deferred gap.

Vale's config/styles/wrapper now ship inside the plugin itself: a
canonical copy in agent-audit/assets/vale/ (Kyberforge + KyberforgeCopilot,
the superset agent-audit needs) and a smaller duplicate in
skill-audit/assets/vale/ (Kyberforge only) — per the no-cross-skill-path
rule already established for plugin cache-installs. Both skills resolve
these relative to their own directory, same as scripts/validate.sh
already does.

A new root .pre-commit-hooks.yaml exposes both copies plus
skill-size-check so any external repo can enforce the same rules via
`repo: <this-repo-url>, rev: <tag>` in its own pre-commit config,
independent of Claude Code entirely — the same mechanism covers CI. This
repo's own pre-commit hook now consumes the identical plugin-bundled
copies via repo: local (not a third root copy, and not a pinned
self-reference, which would lint working-tree edits against the last
tagged release instead of the change being made). Split into
vale-audit-prefilter-skill/-agent hooks after confirming, by diffing the
full corpus against both old and new config before deleting the old
files, that one combined hook pointed at only one copy silently 0-file-
skips the other file type.

scripts/check-vale-style-sync.sh guards the two copies against drift,
wired at pre-push alongside check-manifests.

 A standalone, repo-agnostic plugin (`plugins/lint/`) for configuring and running linters — not scoped to kyberforge's own meta-tooling. First linter is Vale (prose style linting), split into two skills per the git/gitea per-concern pattern: `vale-config` (setup — `.vale.ini`, `StylesPath`, styles) and `vale-run` (invoke Vale, interpret/report findings). A `lint-runner` agent composes these for isolated-context lint sweeps; it is report-only (no `Edit` tool) — it flags findings, it does not rewrite prose. Vale's research docs (`docs/research/docs/vale/`) moved from `plugins/kyberforge/` to `plugins/lint/` to keep the provenance chain same-plugin.
 
 ### Vale audit prefilter (skill-audit / agent-audit)
-Wiring Vale as a deterministic prefilter for `skill-audit`/`agent-audit`'s Description dimension (ADR motivation: issue #84) is repo-specific, not part of the generic `lint` plugin, so its config lives at the repo root rather than inside `plugins/lint/`: `.vale.ini` plus a custom `Kyberforge` style (`styles/Kyberforge/`) covering description-opener banning ("This skill/agent..."), vague-capability wording ("helps with", "utilize", ...), and generic "see references/ for details" padding — and a `KyberforgeCopilot` style (`styles/KyberforgeCopilot/`) scoped only to `.agent.md` files for the Copilot-only "Use proactively has no effect" check. Every rule is `level: error` and every alert is a FAIL — no ignorable tier, same as shellcheck, the test suite, and conventional-pre-commit. Graded severities do not work here: Vale's exit code keys on `error` alerts alone, so `warning`/`suggestion` rules exit 0 and pre-commit swallows the output of a passing hook, leaving them invisible and blocking nothing. `MinAlertLevel` and `--minAlertLevel` are correspondingly absent from `.vale.ini` and the hook, being no-ops under this model. Vale covers the pattern-matchable sub-checks named in issue #84 (imperative opener, vague filler, `Use proactively`, generic reference-pointer padding) plus, per ADR-0013, one body-wide prose-pattern check ("There is/are" sentence openers) — everything else about body discipline (defaults-vs-menus, why-rationale, non-pattern-matchable judgment calls), near-miss exclusion strength, and control calibration stays LLM judgment.
+Wiring Vale as a deterministic prefilter for `skill-audit`/`agent-audit`'s Description dimension (ADR motivation: issue #84) is repo-specific, not part of the generic `lint` plugin, so it doesn't live in `plugins/lint/` — but per ADR-0014 it also doesn't live at the repo root anymore. Two copies live inside `plugins/kyberforge/`, one per skill, since a plugin's cache-install only copies each skill's own files (no cross-skill sharing): `plugins/kyberforge/skills/agent-audit/assets/vale/` is canonical (`.vale.ini` plus a custom `Kyberforge` style covering description-opener banning ("This skill/agent..."), vague-capability wording ("helps with", "utilize", ...), and generic "see references/ for details" padding — and a `KyberforgeCopilot` style scoped only to `.agent.md` files for the Copilot-only "Use proactively has no effect" check), and `plugins/kyberforge/skills/skill-audit/assets/vale/` is a smaller duplicate (`Kyberforge` only, scoped to `SKILL.md`) kept in sync by `scripts/check-vale-style-sync.sh` (pre-push). A root-level `.pre-commit-hooks.yaml` exposes both copies (plus `skill-size-check`) so any external repo can enforce the same rules via `repo: <this-repo-url>, rev: <tag>` in its own `.pre-commit-config.yaml` — pre-commit clones the pinned rev into its own cache, independent of whether Claude Code or the `kyberforge` plugin is installed at all, and the same mechanism covers CI (`pre-commit run --all-files`). This repo's own `vale-audit-prefilter-skill`/`-agent` pre-commit hooks consume the identical plugin-bundled copies via `repo: local` (not a third root copy, and not a pinned self-reference — a pinned self-reference would lint working-tree edits against the last tagged release rather than the change being made). Every rule is `level: error` and every alert is a FAIL — no ignorable tier, same as shellcheck, the test suite, and conventional-pre-commit.

-Both skills' Step 1, and the `vale-audit-prefilter` pre-commit hook, call `scripts/vale-wrap.sh` rather than `vale` directly — a workaround for a confirmed Vale 3.15.2 limitation (see `vale-config`'s Gotchas): `text.frontmatter.description` silently stops matching once the description is a YAML block scalar (`>`/`|`) spanning 2+ physical lines, which is how most skills/agents in this repo write it. The wrapper flattens the description to one physical line in a scratch copy (padding with blank lines so every other line number is unchanged) before handing off to real `vale`; single-line descriptions pass through untouched; a relative `--config` path resolves against the caller's cwd, matching bare `vale`, not against the repo root. `tests/test-vale-wrap.sh` regression-tests this. `.vale.ini`'s section globs are path-agnostic (`[**/SKILL.md]`, `[**/agents/*.md]`, `[**/*.agent.md]`) and do no scoping: Vale's `*` crosses `/`, so the older `plugins/*/`-prefixed globs already matched `plugins/*/docs/research/examples/**/agents/*.md` and `plugins/*/skills/*/assets/templates/SKILL.md`. Scoping comes from the pre-commit hook's `files:` regex, `^plugins/[^/]+/(skills/[^/]+/SKILL\.md|agents/[^/]+\.md)$` (single-segment, not `.*`, since pre-commit invokes it automatically against whatever staged files match rather than a manually-scoped target), and from the audit skills passing one explicit file per invocation. The path-agnostic globs also close a silent false negative: a skill outside `plugins/` (e.g. project-scope `.claude/skills/foo/SKILL.md`) matched no section, so Vale reported 0 files and exited 0 — which the audits read as clean. Both audits now treat a 0-file Vale run as NOT RUN and fall back to full LLM judgment.

Each `.vale.ini`'s section globs are path-agnostic (`[**/SKILL.md]` for skill-audit's copy; `[**/agents/*.md]`/`[**/*.agent.md]` for agent-audit's) and do no scoping on their own: Vale's `*` crosses `/`. Scoping comes from each pre-commit hook's own `files:` regex — `^plugins/[^/]+/skills/[^/]+/SKILL\.md$` for `-skill`, `^plugins/[^/]+/agents/[^/]+\.md$` for `-agent` (split into two hooks precisely because one combined hook pointed at only one copy would silently 0-file-skip the other file type) — and from the audit skills passing one explicit file per invocation. A skill outside `plugins/` (e.g. project-scope `.claude/skills/foo/SKILL.md`) matches no glob section, so Vale reports 0 files and exits 0 — which the audits read as clean. Both audits treat a 0-file Vale run as NOT RUN and fall back to full LLM judgment.
 
-This scope expands per ADR-0013: one cherry-picked low-noise `write-good`/`alex` rule landed in `styles/Kyberforge`, `Kyberforge.SentenceOpenerThereIs` (22 held-out hits, both in-corpus hits clean rewrites, zero suppressions). A second, `Kyberforge.VagueQualifier`, was cherry-picked and then deleted: 2 hits across the 41 skill/agent files, one marginal and one an unfixable false positive (`caveman/SKILL.md` quotes `of course` as an example of filler — a mention, not a use) that forced the repo's only Vale suppression comments. Also new is a sibling pre-commit hook, `skill-size-check` (`scripts/skill-size-check.sh`), enforcing agentskills.io's 500-line/5,000-token `SKILL.md` ceiling — failing only above 500 lines, matching `skill-audit/scripts/validate.sh`'s `<= 500` pass — scoped to `^plugins/[^/]+/skills/[^/]+/SKILL\.md$` only, same as `vale-audit-prefilter`, so it never lints `docs/research/examples/` reference skills. File scope (`SKILL.md` + agent files) and enforcement model (rules land directly in `styles/Kyberforge`, blocking immediately, no trial tier) stay unchanged; governance.md/CONTROLS.md were evaluated and excluded as rule sources (nothing prose-pattern-matchable to mine). House convention: banned phrasing that must be mentioned rather than used goes in backticks or a fenced code block — Vale skips code spans and fences, so no suppression is needed; inline `<!-- vale Rule = NO -->` (HTML-comment form; the MDX `{/* */}` form does not work in plain Markdown) is the fallback only where backticking is impossible.
