fix(kyberforge): resolve PR #144 review and audit round 1

- factory-audit: no-op hooks, ./ after interpreters, split-quote and
  spaced ${PLUGIN_ROOT} paths, camelCase events in Claude-targeted flat
  files, case-insensitive routing stems, and non-string YAML keys are
  now caught; input: forms and prompt boundary clauses align with
  primitive-author; bats 347 -> 367
- primitive-author: routing forms, quoting guidance, install exit on
  hidden Unicode, argument-hint exception
- forge: drop duplicated gotcha, fit description and body budgets (#143)
- skill-author: primitive-author boundary, Claude-only env vars
- hook: exit unless CLAUDE_PROJECT_DIR is set, so Copilot/Codex never
  run apm update; ADR-0019 correction, ADR-0025 amendment, docs fixes

 - apm checks almost nothing here. Invalid JSON is skipped without a word, an all-lowercase event deploys and never fires, and a missing script only warns — so `apm install` exiting 0 says nothing about whether the hook works. Never cite a clean install as evidence against a finding.
 - Copilot receiving a Claude-shaped file is not a finding. apm renders one source for every target and documents that it owns the per-target shape; whether Copilot CLI honours a nested entry or `matcher` is unverified upstream, not a defect in the file.
+- Quoting is not the fix for a script path with a space. apm rewrites a whole-token-quoted `"${PLUGIN_ROOT}/scripts/x.sh"`, but still stops reading the path at the space; the only fix is a path without one.

+Its findings become the `### Structure` dimension, FAILs and SUGGESTIONs both, at the tier the script assigned: JSON validity, the wrapped-or-naked shape, event lists and nested handler lists (the checks whose failure makes the Copilot install fail), a file contributing no entries (no events, only empty event lists, or an entry with no handler), event names that never fire, referenced scripts that are missing, outside the package, not executable when run directly, or referenced by an absolute, bare relative, `../`, split-quoted or space-containing path apm will not bundle correctly, deprecated filename routing, and `${CLAUDE_PLUGIN_ROOT}` where `${PLUGIN_ROOT}` would do. Script references are read with apm 0.28.0's own patterns: `${PLUGIN_ROOT}/…` only when the path follows the token directly, up to the first whitespace or quote, and `./…` anywhere in the command, including after an interpreter. A camelCase event outside Claude's rename map FAILs in a Claude-shaped file, and in a flat Copilot-shaped file too whenever the nearest `apm.yml` above the file targets Claude — no `target:`/`targets:` means every target. It exits **0** with no FAIL, **1** on real findings, **2** when it never ran — report that as `### Structure` unverified, quoting the stderr reason.
 
 There is no provenance and no Vale step: a hook carries no `source_keys` and no prose.

+Four tiers deliberately differ from `primitive-author`'s checklist or the research's. Do not re-tier them by judgment:
 
 - A hook file directly under a package-root `hooks/` passes. apm discovers both `.apm/hooks/` and `hooks/`, and this audit may target a third-party package; `primitive-author` authors only in `.apm/hooks/`.
 - Deprecated filename routing is a SUGGESTION, matching the author's Should: the research allows it when deprecated routing is intended.
 - A non-executable script run as the command's first token is a FAIL, stricter than the research's Should, because it fails every time it fires.
+- A split-quoted `"${PLUGIN_ROOT}"/x.sh` or a script path containing a space is a FAIL, stricter than the author's Should 10: apm leaves the first unrewritten and cuts the second at the space, so either deploys a hook that fails every time it fires.

 - SUGGESTION: a tool event (`PreToolUse`, `PostToolUse`) or `SessionStart` with no `matcher` — Claude receives `"*"`. A `matcher` on an event Claude ignores it for (`Stop`, `UserPromptSubmit`) is inert, not wrong.
 - SUGGESTION: a PascalCase event name that is not a real Claude Code event (a misspelling deploys verbatim and never fires; the script cannot tell a typo from an event it does not know).
 - SUGGESTION: `bash`/`powershell`/`timeoutSec` keys in a Claude-shaped file — they render, but leave stray keys in `settings.json`.
-- SUGGESTION: an unquoted script path that could contain spaces.
 - SUGGESTION: a helper `.json` file in the hook directory without a `hooks` key — Copilot's loader scans the bundled scripts directory and rejects it. Keep helper configuration non-JSON.
