* fix(proxy): keep capture persistence off the main thread
Move bundled capture writes, payload compression, and inspection through the canonical SQLite workers. Preserve shipped synchronous SDK compatibility and exact database, maintenance, and accepted-callback ownership.
Drain accepted capture before shutdown, release partial proxy startup, and charge queued payload preparation through the existing broker. Preserve schemas, stored bytes, and retention. Related: #148336.
