fix(lint): resolve round-1 and round-2 review findings on the Vale prefilter

Addresses PR #85's outstanding review items after grilling the open
questions against ADR-0013/CONTEXT.md/ADR-0010:

Blocking fixes:
- vale-wrap.sh: replace json.dumps() escaping (which silently defeated
  Vale's frontmatter scope on any description containing a quote,
  backslash, or non-ASCII char — ~58% of the corpus) with a single-quoted
  YAML scalar, substituting a Unicode right single quote for embedded
  apostrophes rather than '' doubling (Vale's frontmatter scanner isn't a
  full YAML parser and silently truncates on '' too).
- vale-wrap.sh: fix a blank-line-inside-a-folded-description truncation
  bug via indentation-based, blank-line-tolerant body capture; narrow
  flattening to `>`-style scalars only (`|` already works unflattened).
- skill-audit/agent-audit Step 1: make the vale-wrap.sh invocation
  cwd-independent via git rev-parse --show-toplevel, fixing a bug where
  no single cwd satisfied all three Step 1 commands.
- styles/Kyberforge/VagueQualifier.yml: prune 17 tokens verified
  false-positive-dominated on this repo's own voice via a real corpus
  sweep (obvious, clearly, usually, several, simple, easy, completely,
  simply, tiny, etc.), keep 13 with real or unattested noise. Revert the
  28 prose "fixes" those tokens drove across 14 skill files back to their
  original, correct wording, including a functional regression to
  caveman/SKILL.md's own filler-word list (a mention, not a use) — now
  guarded with vale-off comments against recurrence.

Gaps:
- --minAlertLevel=warning on the pre-commit hook and Step 1 invocation
  so warning-level rules actually surface, without collapsing the
  FAIL/SUGGESTION severity mapping skill-audit/agent-audit rely on.
- vale-wrap.sh: fix --config=<path> equals-form, absolute-path silent
  no-op, and a zero-file-argument stdin hang.
- Route vale-run and lint-runner through a documented wrapper script
  when a target repo has one, instead of unconditionally recommending
  bare `vale`.
- Wire Kyberforge.VagueQualifier/SentenceOpenerThereIs into skill-audit/
  agent-audit's dimension-mapping prose (Body discipline).
- Add plugins/lint/sources.md provenance for lint-runner (ADR-0010).
- Sync both marketplace.json lint-entry descriptions with plugin.json.
- Retune skill-size-check.sh's MAX_WORDS 5000->2900 (measured ~1.6-1.7
  tokens/word on this repo's corpus, the old value gated at ~8,500
  tokens against a stated 5,000 ceiling); fix the >/>= line-count
  boundary and wc -l undercount on files with no trailing newline.
- Document the vale binary as a Setup prerequisite in AGENTS.md.
- Fix SentenceOpenerThereIs's dead regex alternative and add a real
  sentence-start anchor/scope.
- Fix a stale docs/research/docs/vale/ index pointer in kyberforge's
  docs README (moved to plugins/lint/ in e1a5403).
- Rewrite ADR-0013's Consequences section past-tense to describe what
  actually landed, and record the styles-portability limitation
  (repo-root placement stays intentional; deferred to a separate
  session per this PR's review).

Test coverage: 9 new vale-wrap.sh fixtures (quotes, backslash/unicode,
blank-line paragraphs, --config= form, zero-arg/absolute-path handling,
literal-block no-regression) and boundary-pair tests for
skill-size-check.sh's line/word ceilings.

bash tests/run-tests.sh: 9 scripts + 125 bats assertions, all passing.
scripts/check-manifests.sh and claude plugin validate --strict: clean.

 The script accepts either the CC file or the Copilot file. It detects provider from extension, derives the counterpart, and runs all structural checks.

Findings about CC-only fields in a Copilot file, Copilot-only fields in a CC file, plugin-silently-ignored fields, body length, or subagent-unavailable tools → `### Provider safety`.

-Run `vale-wrap.sh` from the repo root against both files of the pair (not just the one passed in), using `.vale.ini`. `Kyberforge` applies to both files; `KyberforgeCopilot` applies to the `.agent.md` file only, since its one rule (`Use proactively`) flags CC-specific phrasing that's meaningless in a Copilot description — there's nothing to flag in the CC file, so it isn't scoped there. Map `error` → `FAIL` and `warning`/`suggestion` → `SUGGESTION` in the `### Description` / `### Body` dimensions, citing the rule ID (e.g. `KyberforgeCopilot.ProactivePhrase`). Skip and fall back to Step 2 judgment if vale or `.vale.ini` is unavailable.

 `validate-provenance.sh` validates the provenance chain between the agent pair's `source_keys` and the plugin-scoped `sources.md` (plugin root — see ADR-0010). It exits 0 silently for non-plugin-scope agents and when no provenance data exists. Note FAILs from this script for the `### Provenance` dimension — surface them verbatim with Why and Fix.
