oh-my-codex v0.12.3

Follow-up patch release for $team prompt-routing correctness and duplicate team launch teardown

0.12.3 is a tight follow-up to 0.12.2 that ships PR #1364, which was intended to land in 0.12.2 but finished its conflict resolution after the 0.12.2 cut. This release closes that gap so operators get the corrected $team keyword routing and the duplicate same-name team launch guard.

Highlights

• $team detected in UserPromptSubmit now seeds root team-state.json and nudges operators toward omx team ... / omx team --help instead of silently misrouting the prompt.
• startTeam now rejects duplicate active same-name team launches with a team_name_conflict error before mutating team state or provisioning worktrees.
• Release metadata and collateral are aligned to 0.12.3.

What’s Changed

Fixes

• seed root team-state.json when $team is detected in UserPromptSubmit and route operators toward omx team ... / omx team --help (PR #1364)
• reject duplicate active same-name team launches before state mutation or worktree provisioning, preserving the existing team config and tasks (PR #1364)

Changed

• bump release metadata from 0.12.2 to 0.12.3 across Node/Cargo manifests, changelog, and release collateral

Verification

• npm run build
• npm run lint
• npm test
• npm run smoke:packed-install

Remaining risk

• This verification is still local; it is not a full GitHub Actions matrix rerun.
• PR #1364 touches live $team keyword handling and startTeam state seeding; post-release monitoring should watch for any regressions in prompt-driven team launch paths.
