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/

+## Sources
+
+- PR #9821: https://github.com/anomalyco/opencode/pull/9821
+
+## Do Not Translate (Locale Additions)
+
+- `OpenCode` (preserve casing in prose; keep `opencode` only in commands, package names, paths, or code)
+- `OpenCode CLI`
+- `CLI`, `TUI`, `MCP`, `OAuth`
+- Commands, flags, file paths, and code literals (keep exactly as written)
+
+## Preferred Terms
+
+No PR-backed term mappings yet. Add entries here when review PRs introduce repeated wording corrections.
+
+## Guidance
+
+- Prefer natural Danish phrasing over literal translation
+- Keep tone clear and direct in UI labels and docs prose
+- Preserve technical artifacts exactly: commands, flags, code, URLs, model IDs, and file paths
+
+## Avoid
+
+- Avoid translating product and protocol names that are fixed identifiers
+- Avoid mixing multiple Danish terms for the same recurring UI action once a preferred term is established
