fix(codex): stop bootstrap re-firing on resume (match Claude startup|clear|compact)

Bug: the SessionStart hook matcher in hooks-codex.json included "resume",
causing the superpowers bootstrap to re-fire on every Codex session resume.

Fix: align with Claude's hooks/hooks.json matcher "startup|clear|compact":
- drop "resume" (the bug: resume should not trigger re-bootstrap)
- add "compact" (so bootstrap re-injects after context compaction, like Claude)

Before: "matcher": "startup|resume|clear"
After:  "matcher": "startup|clear|compact"
