feat: YAML pipeline template autocomplete (AzDO + GHA)

- Add scripts/sync_pipeline_templates.py — scans LRU AzDO and GHA template
  repos; outputs unified pipeline_templates_catalog.json (48 templates: 45
  AzDO + 3 GHA)
- Add scripts/template_sources.yml — source config (AzDO alias, GHA org)
- Add pipeline_templates_catalog.json — baked catalog (49 KB)
- Add ilsp/yaml_lsp/catalog.py — PipelineTemplateCatalog with completion item
  generators for template paths, param names, allowed values, GHA inputs
- Add ilsp/yaml_lsp/proxy.py — async WS↔TCP bridge with LSP frame buffering,
  per-connection document tracking, AzDO/GHA context detection, and completion
  injection (LRU items sortText 0_, standard items downgraded to 9_)
- Wire yaml_ws_handler into server.py (replaces raw _ws_proxy call)
- Load PipelineTemplateCatalog at startup; reload + health report template count
- Update push_catalogs.sh to push pipeline_templates_catalog.json
- Update Dockerfile to bake pipeline_templates_catalog.json as image fallback
- Add tests/test_yaml_catalog.py (14 tests) + tests/test_yaml_proxy.py (18 tests)
  All 67 tests green
