fix: architecture review corrections — CONTEXT.md trim and eval backtrack verification

- Remove Fleet, Symbolic oversight, and Data classification tiers from
  CONTEXT.md glossary: Fleet is Phase 2 only; the other two duplicate
  always-on governance.md content
- Drop now-stale governance test assertions for the removed terms
- write-skill eval: add section-ordering assertion; fix duplicate prompt
  across two deterministic tests
- write-eval eval: tighten plan-shown assertion to require per-case
  detail (query + type), not just "a list of test cases"
