chore: initial commit — planning docs and omc project context

Greenfield setup for luke_scribe (local STT transcription API). No source
code yet; this captures the completed design phase so teammates can ramp
through oh-my-claudecode.

Includes:
- .omc/plans/consensus-luke-scribe-stt-api.md — consensus impl plan v2.2
- .omc/specs/deep-interview-luke-scribe-stt-api.md — deep-interview spec
- .omc/artifacts/ask/{codex,gemini}-*.md — external review (CCG)
- .omc/project-memory.json — omc project memory
- opencode.json, .claude/settings.json — shared tooling config
- .gitignore — excludes ephemeral omc state/session logs and local settings
