* fix: resolve all outstanding issues across hawk + eyrie

hawk:
- C4: SQLite context.Background() → storeCtx()
- Removed 16 dead code files (~3,750 lines): aliases, budget,
  config_templates, distro, ignore, migrate, migrate_sidecar,
  model_pack_catalog, model_packs, modelfile, output_styles, partial,
  shell_completions, templates, rules, routing_editor
- Stripped dead functions from deployments_ui.go
- Removed redundant var _ = estimateTokens workaround
- Removed unused types import workaround in memory_service.go

eyrie:
- C4: silenced resp.Body.Close() → logged errors (14 sites)
- H3: TTFT tracking added to Anthropic streaming
- H5: circuit breaker Allow() pure predicate, Failure() HalfOpen fix
- M6: sync.Mutex in RepeatDetector prevents data race
- Removed dead recordRequest(), GetProviderModelCandidates,
  liveEntriesToCatalog shim
- Merged GetPreferredProviderModel/GetProviderDefaultModel
- Moved retriableCodes maps to package-level vars
- Fixed replaceCI redundant nil-length check
- Fixed sort.SliceStable race in shrink (moved to init())
- Updated all callers and tests

* fix: address PR review comments

- sqlite_store.go: revert ctx/storeCtx dead code (always nil)
- daemon.go: constantTimeEqual uses subtle.ConstantTimeCompare + len check
