docs: re-anchor Shape A examples away from Codex

hooks/session-start-codex has had no caller since "Remove Codex hooks"
(#1845) deleted hooks-codex.json and its manifest registration; the
Codex manifest now declares an empty hooks object so Codex registers no
session-start hook at all. The script is Codex-specific dead code —
nothing executes it on Codex or any other harness.

- Delete hooks/session-start-codex.
- tests/hooks/test-session-start.sh: drop the two Codex cases that are
  redundant with the generic session-start tests (nested-format and the
  legacy-warning omission are already covered by the Claude Code cases).
  Re-point the "wrapper dispatches" case to the live `session-start`
  script so run-hook.cmd dispatch coverage — used by Claude Code and
  Cursor in production — is preserved rather than lost.
- docs/porting-to-a-new-harness.md: Codex is no longer a Shape A
  (shell-hook) harness, so re-anchor that worked example to Cursor (a
  live shell-hook harness that demonstrates the same per-harness field,
  schema, and matcher variance) and mark Codex as native skill discovery
  with no session-start hook. Clears the references to the deleted
  hooks-codex.json.
- docs/windows/polyglot-hooks.md: the "check hooks-codex.json" pointer
  referenced a file deleted in #1845; re-point to hooks-cursor.json.

RELEASE-NOTES.md keeps its historical mention of hooks-codex.json (it
accurately records what that release did). The tests/codex-plugin-sync
fixtures build their own synthetic session-start-codex and test the sync
mechanism generically, so they are intentionally left as-is.

-Usage:
-  scripts/package-codex-plugin.sh [options]
-
-Options:
-  --output PATH            Write archive to PATH.
-                           Default: ../_tmp/sup-codex-packaging/superpowers-VERSION.zip
-  --format FORMAT          Archive format: zip or tar.gz. Default: zip.
-                           If --output ends in .zip, .tar.gz, or .tgz, that
-                           extension is used when --format is omitted.
-  --metadata-source PATH   Prior official package directory, .zip, or .tar.gz used to
-                           seed skills/*/agents/openai.yaml.
-                           Default: ../_tmp/sup-codex-packaging/superpowers,
-                           falling back to superpowers.zip, then superpowers.tar.gz
-  --ref REF                Git ref to package. Default: HEAD.
-  --allow-dirty            Permit a dirty working tree. The archive still uses --ref.
-  --keep-stage             Print and keep the temporary staging directory.
-  -h, --help               Show this help.
-
-The archive is rootless: .codex-plugin/, assets/, skills/, README.md, LICENSE,
-and CODE_OF_CONDUCT.md sit at the archive root. Source-only repo files, hooks, tests,
-docs, and other harness manifests are intentionally not shipped.
