Set accounts.disableQueue = true on AccountManager during initialization:
- Applies to all accounts automatically
- No need for temporary queue toggling in individual operations
- Makes all bunker requests instant (no internal queueing)
Removed temporary queue disabling from bookmarkProcessing.ts since
it's now globally disabled.
Updated Amber.md to document the global approach.
This eliminates the root cause of decrypt hangs - requests no longer
wait in an internal queue for previous requests to complete.
Added findings about applesauce-accounts queue issue:
- Queue MUST be disabled for batch decrypt operations
- Default queueing blocks all requests until first completes
- This was the primary cause of hangs and timeouts
- Updated performance improvements section with all optimizations
- Updated conclusion with key learnings

- Add withTimeout and mapWithConcurrency helpers in utils/async.ts
- Refactor collectBookmarksFromEvents to decrypt with 6-way concurrency
- Public bookmarks collected immediately, private decrypted in parallel
- Each decrypt wrapped with 30s timeout safety net
- Document non-blocking publish and concurrent decrypt in Amber.md
