This database is locked error spiked across the 0.56.0 → 0.58.0 extension range. Multiple sibling buckets share the same SQLite lock failure in nS.tryAddOrUpdateFile / onFileChanged / onFileAdded / onFileDeleted (file-watcher indexing path), coalesced into this issue:

Bucket	Users	Spike	Platforms
1626a288 (rep)	156	14.2x	linux
e3e71be8	146	14.6x	linux, darwin
243cda84	126	14x	linux, win32
c3b56109	98	14x	linux

d2c3e071	33	8.3x	darwin
65bfe103	26	13x	darwin
8e4eb0f2	20	10x	darwin

Predominantly Linux/macOS. Root cause appears to be concurrent writes to the Copilot SQLite index from the file-watcher event handlers.
