feat(aircoding): AirCoding V2 baseline — deterministic multi-agent architecture

Forked from OpenCode v1.17.4 with multi-agent system:
- 5 agents: aircoding, scheduler, worker, architect, reviewer
- Deterministic DAG scheduling engine (coordinator_tick)
- Tool whitelists as hard enforcement
- AirCoding validation plugin
- V1 requirements: C4 docs, ADR, AGENTS.md, debug-log.md
- Design documents in docs/

packages/ui/src/components/dock-prompt.stories.tsx

+
+Use with form controls or confirmation buttons in the footer.
+
+### API
+- Required: \`kind\` (question | permission), \`header\`, \`children\`, \`footer\`.
+- Optional: \`ref\` for measuring or focus management.
+
+### Variants and states
+- Question and permission layouts (data attributes).
+
+### Behavior
+- Pure layout component; behavior handled by parent.
+
+### Accessibility
+- Ensure header and footer content provide clear context and actions.
+
+### Theming/tokens
+- Uses \`data-component="dock-prompt"\` with kind data attribute.
