fix(daemon): decouple trace ingestion from side effects

[svarlamov]

Summary

• move trace normalization and repository side effects off the trace socket ingress tasks
• run family and global actor work on blocking workers while preserving per-family ordering
• keep trace accept and frame handoff responsive under deliberately slow side effects

Tests

• slow-side-effect regression proving unrelated trace progress
• stalled and silent trace connection coverage
• full task test, task lint, task fmt, and task build on the completed stack

Depends on #1980.
