- Bump workspace.package.version 0.8.33 -> 0.8.34 across all 14 crates
- Bump npm wrapper version + deepseekBinaryVersion pin
- Update docs/TOOL_SURFACE.md "Current surface" + docs/ARCHITECTURE.md
  current-surface references; historical "removed_in"/"v0.8.33 began
  moving" wording stays as fact
- Update web/lib/facts.generated.ts version pin
- Draft [0.8.34] CHANGELOG section covering the 135 commits since 0.8.33
  (prefix-cache stability, bundled skills, Kitty/Ghostty notifications,
  theme picker, chunked tool dispatch, MCP session-id persistence,
  cost-calc reasoning tokens, and the in-flight internal cleanup)
- Remove stale repo-root development artifacts:
  * TAKEOVER_PROMPT.md (v0.8.6 handoff, 3 minors stale)
  * PROMPT_ANALYSIS.md (v0.8.13-era prompt audit doc)
  * DEPENDENCY_GRAPH.md (claimed monolith layout, predates 14-crate split)
  docs/ARCHITECTURE.md already contains the live crate map.
- Update CONTRIBUTING.md to reference docs/ARCHITECTURE.md for build
  ordering instead of the removed DEPENDENCY_GRAPH.md
