Restrict the automatic `uninstall` legacy Codex sync fallback to homes
that have a legacy ownership manifest (`~/.codex/ecc/legacy-sync-state.json`).
Marker-only AGENTS.md files are no longer auto-detected as legacy installs,
so a normal `uninstall` will not silently modify user-owned instructions.
The explicit `--legacy-codex-sync` flag still handles marker-only and
manifest-backed cleanup.
Also:
- Track the AGENTS.md path in removedPaths when a marker block is removed.
- Refactor codex home resolution into a helper.
- Add regression tests for marker-only auto vs. explicit behavior.

Tighten uninstall auto-detection so it only falls back to the legacy
sync-ecc-to-codex.sh path when there is an ownership manifest
(~/.codex/ecc/legacy-sync-state.json) or an ECC marker block in
~/.codex/AGENTS.md. Previously a clean Codex home with unrelated prompt
files could be misclassified as a legacy install, causing uninstall to
skip normal install-state reconciliation and exit with a partial warning.
Also make the no-state fallback return 'not-found' when there is no
marker to remove and no candidate files to clean, and make explicit
--legacy-codex-sync report the same on a clean home.

Use no-follow file descriptors for legacy Codex snapshots, verification, restoration, and marker cleanup. Quarantine candidate removals and verify inode identity before deletion.
Carry the lifecycle runner as a verified artifact so privileged release workflows never dynamically check out and execute an output-selected revision.
