feat(codex): update placemat for Codex CLI v0.162.0

[dommango]

Summary

Syncs the Codex CLI placemat from v0.161.0 to v0.162.0.

• Version poll: api.github.com is gated in the routine sandbox, so I fell through to the declared fallbacks — releases.atom (found rust-v0.162.0, rust-v0.163.0-alpha.1/.2) paired with the /releases HTML page to confirm rust-v0.162.0 is the newest tag that is neither prerelease nor draft. Cross-checked against registry.npmjs.org/@openai/codex → dist-tags.latest = 0.162.0. Match.
• Installed @openai/codex@0.162.0 and used codex --help / codex features list / codex agents --help to verify CLI surface directly against the binary, per the pipeline's "trust the binary over the docs" trap.
• Read the GitHub release body for rust-v0.162.0 above the ## Changelog heading (the designated changelog source) for the three items that touch existing placemat rows.

Changes

• card-keys → /tui (still unverified): added a 4th note for v0.162.0's transcript-block navigation/copy via /copy, a Ctrl+Insert copy-selection shortcut, and adjustable mouse-wheel scroll speed — following the same "pending confirmation against the CLI reference" pattern already used for this row's v0.156.0/0.158.0/0.159.0 notes, since developer-commands.md still doesn't document this TUI behavior.
• card-cli → codex agents: added a note for task pinning in the Command Center (p key, shared Pinned group when the server supports it) — verified only via the release notes, not --help, so worded the same way.
• card-cli → --worktree: added a second note for the new tooling to create/list managed worktrees for trusted local projects.
• Bumped .release-tag / .print-head / footer sync date to v0.162.0 / 2026-10-08 (all three agree).
• Added the Codex CLI v0.162.0 changelog section; regenerated changes.json and feed.xml via node scripts/build-changes.js codex.

Deliberately left out

• Several bug-fix and chore bullets (Linux sandbox startup, Windows drive-letter access, Retry-After handling, signed PowerShell installer, etc.) don't map to any documented placemat row, so no entry was added for them.
• "Custom Responses-compatible model providers... live web access and remote compaction" and Code Mode's opt-in ranked tool search (code_mode_tool_search, still under development/disabled in codex features list) introduce no new config.toml key — re-fetched config-reference.md and diffed it against sources.json → inventory.settings; the only genuinely new key was features.prefer_mxc, which is internal/under-development and not tied to anything in this release's notes, so I didn't add a row for it either.
• No new slash commands, settings keys, or hook events needed sources.json → inventory re-extraction, since nothing in this release introduced a new row — only notes on existing ones.

Checklist

• node scripts/build-changes.js codex — regenerated clean
• node tests/placemat.test.js codex — 54 passed, 0 failed
• Release tag / print-head / footer sync date agree (v0.162.0 / 2026-10-08)
• No existing unverified rows were promotable (re-checked /tui against the newly fetched developer-commands.md; still undocumented there)
• No other agent directory touched

Self-review (Step 8) done against the sources above; independent code-review skill pass to follow per the merge gate.
