fix: enable Codex remote rooms on Windows in v0.1.30

[wudd15]

Enable Codex sessions to use configured remote rooms and bump the v3 preview from 0.1.24 to 0.1.30. Previously, abg join saved the directory mapping but Codex had no room tools, and a daemon started before joining kept its inactive room configuration.

Add member lookup, explicit private/broadcast messaging, and a bounded incoming-room inbox. Refresh the mapping before each TUI initialization and keep Codex temporary helper threads from replacing the active user thread. Preserve room tool registration across daemon restarts, validate recipients and originating sessions, and prevent automatic room reply loops.

Resolve native codex.exe on Windows, hide background app-server windows, and fix Windows build path and executable-bit checks. Include usage documentation, regression tests, an opt-in live Codex smoke test, and synchronized plugin bundles. The version update covers package.json and both plugin manifests.

Validation: TypeScript checking, targeted room/Windows launcher tests, bundle synchronization and version checks, local global installation, and a live isolated-broker Codex test covering late join, member lookup, directed sending, incoming notices, and no automatic reply. An actual Codex TUI successfully queried the remote tas room after the fixes. The broader adapter tests have three Windows-specific failures also reproduced on the unchanged baseline; the full repository suite was not run.

Existing threads created without room tools require --new once after upgrading. Room membership does not imply online presence, and message submission is not a delivery receipt.
