v0.9.9

feat: v0.9.9 — operational params, parent hierarchy, shared noise filter

Phase 1-5 unification with llm-wiki-v3:
- Add operational_params table in DuckDB (timeout/cron/retry/pool extraction)
- Value validator: reject type declarations, keep real config values (95% signal)
- Add group_parents() with quality gate (skip when >50% modules in "Other")
- Extract noise_filter.py as shared module (297 noise patterns + is_noise_node())
- Refactor cgc_wiki_cli.py to use noise_filter (removed ~100 lines inline set)
- Add ## Operational Parameters section in module_contexts/*.md
- Save parent_groups in modules.json for llm-wiki consumption

Tested on 8 repos: 0 regression, op_params noise 60%→5%.
