Wave 8: tech-debt audits, core unit tests, CLI pipe input (W11.1-W11.7)

- W11.1 context_plugin audit (architect-huang): 3 findings on ABI exception
  safety, strdup null checks, dead g_max_tokens variable. Rating: B.
- W11.2 config audit (engineer-chen): identified 74-line TOML parser
  duplication between config_plugin and config_store, dual-store data
  isolation, dangling c_str() risk. Rating: C.
- W11.3 event_bus + service_registry unit tests (qa-liu): 12 cases total,
  ctest coverage 2 -> 4 targets, 100% pass.
- W11.4 CLI stdin pipe mode (engineer-zhao): isatty detection, single-shot
  inference path with exit codes 0/1/2/3.
- W11.6 scripts/refresh_status.py (engineer-li): 431-line generator that
  scans 16 profile.md + 5 group.md to regenerate STATUS.md.
- W11.7 destructive testing (qa-xu): 10 input scenarios PASS, found bin
  copy mismatch (BUG-1) plus 3 minor UX bugs for follow-up.

Verified: cmake build 0 error, ctest 4/4 pass.
