Adds the third session adapter (after dmux-tmux and claude-history),
normalizing Codex rollout sessions into the harness-neutral
ecc.session.v1 snapshot. Reads ~/.codex/sessions rollout JSONL,
derives objective (skipping the AGENTS.md preamble + leading message
UUID), model, originator, worktree cwd, and best-effort git branch.
This is step 1 of ECC-2.0-SESSION-ADAPTER-DISCOVERY (move the
abstraction beyond tmux + Claude-history) and supports the
wrap/adapt control-pane strategy: ECC reads sessions from any
harness rather than owning one UX.
- scripts/lib/session-adapters/codex-worktree.js: adapter + rollout parser
- canonical-session.js: normalizeCodexWorktreeSession
- registry.js: register adapter, codex/codex-worktree target types
- tests/lib/session-adapters-codex.test.js: 4 tests (unit + registry routing)
- Registry accepts { type, value } structured targets
- Add --list-adapters and --target-type CLI flags to session-inspect
- Export adapter type from claude-history and dmux-tmux adapters
- 71 new session adapter tests, 34 new session-inspect tests
- All 1142 tests passing
