fix: Codex wrong-repo + routing table to body + 900-char guard (v0.11.19.0)

- Add -C "$(git rev-parse --show-toplevel)" to all 14 codex exec calls
  so Codex always runs in the correct repo (fixes Conductor multi-workspace bug)
- Move skill routing table from description to body in SKILL.md.tmpl
  (description was already shortened on main; routing table was missing from body)
- Add 900-char warning threshold test for Codex descriptions
- Bump version + sync package.json
