fix(3583): normalize retired colon-form commands in generated Claude/Qwen/Hermes SKILL.md bodies (#3629)

* Add first-class grok runtime support (maps to ~/.agents); wire installer, runtime-homes.cjs and sync-skills; update Grok Build engine in local ~/.agents to latest; record session progress in discussion doc

* Normalize gsd colon references to hyphen in generated Claude SKILL.md bodies using the shared transformer. Fixes #3583.

* Refine #3583 implementation after review: cache command names, improve tests, clean up comments

* Harden gsd colon-to-hyphen transformer with bidirectional word boundaries and body-only regression guard

* Track quick-wins batch status and local session notes for #3583/#3579 handoff

* Port installer robustness (hoist copyLibDir + selective Codex hooks) from 3579 to make Codex tests pass on this branch. Fixes ReferenceError and prevents extra hook pollution in Codex installs.

* Restore #3583 transformer wiring and Codex .sh GSD_VERSION branch lost in 50ff8f17 port

Commit 50ff8f17 ('Port installer robustness from #3579') accidentally reverted:
- the top-level require of transformContentToHyphen/readGsdCommandNames
- the body normalization inside convertClaudeCommandToClaudeSkill
- the Codex hook loop's .sh branch with {{GSD_VERSION}} substitution

These were the actual #3583 fix and the Codex half of the #2136 invariant.
Failing tests fixed: bug-2808-skill-hyphen-name, claude-skills-migration #3583
case, bug-2136 Codex .sh substitution.

* Exempt 'sync-skills' slug from docs-parity check (skill dir name in path references)

gsd-sync-skills is an installed Claude skill name and a workflow file but
not a registered slash command. The docs-parity regex catches /gsd-sync-skills
from filesystem path references like ~/.agents/skills/gsd-sync-skills/ in
docs/discussions/grok-build-support-2026-05.md.

Adding to INTERNAL_COMPONENT_SLUGS matches the existing exemption pattern
for 'statusline', 'workspaces', 'graphify-update', etc.

* Restrict hooks/lib/ install to hook-enabled runtimes and managed allowlist

Codex/Copilot/Cursor/Windsurf/Trae/Cline already skip the hooks block but were still copying hooks/lib/ helpers, contradicting the downstream Codex comment. Gate the call on the same runtime check and pass GSD_HOOK_LIB_FILES so install scope matches the uninstall/manifest scope.

+Claude skill install (convertClaudeCommandToClaudeSkill + copyCommandsAsClaudeSkills) now normalizes retired /gsd:<cmd> references in SKILL.md bodies to the canonical gsd-<cmd> hyphen form using the new transformContentToHyphen from the shared fix-slash-commands.cjs transformer. Frontmatter name: was already correct since #2808; body leakage is now eliminated for Claude, Qwen, and Hermes. Added regression guard in bug-2808 test. Fixes #3583.
