Codex re-fires SessionStart with source "compact" after every context
compaction; the summary keeps progress but sheds the bootstrap and any
active skill's instructions — measured July cause of post-compaction
dispatch drift in long SDD runs (with re-injection: 18/18 hook fires,
66/66 post-compaction dispatch tuples correct in a 12.4h stress run).
Codex discovers skills natively at startup, so the hook is silent
there: the compact re-fire is the one unowned lifecycle point.
Adds the plugin-provided hook (hooks-codex.json + session-start-codex,
compact-only, fails open), wires it into the manifest and package,
documents install/trust behavior, updates codex-tools.md with the
re-grounding fallback, and tests the hook lifecycle, manifest, and
archive contents.
Rebuilt from the July codex-spinout-fixes branch, pared to the hook
core: the dispatch-hints layer it used to ride with is superseded by
the merged 2059-2062/2077-2080 stack and is dropped.

Codex reliably triggers skills on its own, and the SessionStart hook
made the UX worse rather than better. Drop the Codex hook config and
its registration in the plugin manifest.
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"
