Final review fixes:
- docs/ARCHITECTURE.md: add kebab-mcp to UI subgraph + directory tree
(CLAUDE.md "add new crate" rule required this; missed in Task 12 doc sync).
- state.rs: replace forward-reference Task 10 comment with current-state
doc (config_path now wired by Task 10 commit 4a30959).
- tools_call_schema.rs: assert capabilities.mcp_server == true (already
pinned in schema_report + cli_schema, this closes the gap in mcp's own
test).
Version bump 0.3.0 → 0.4.0 deferred to separate `chore/bump-v0.4.0` PR
mirroring fb-27 precedent (commit 73f5d73 / PR #105).
