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
