The Cursor provider encodes workspace context into source paths using a
`#cursor-ws=<tag>` suffix (e.g. `state.vscdb#cursor-ws=__orphan__`).
`fingerprintFile` only had a fallback for `:` separators (OpenCode
sessions), so Cursor sources silently returned null on macOS/Linux where
paths contain no colons, causing them to be skipped entirely.
Add a `#` fallback before the existing `:` check. The first `stat()`
on the full path still succeeds for real files containing `#`, so there
is no regression for legitimate paths.
Includes 4 new test cases covering both separators, the combined case,
and the null case for non-existent base files.
Cache normalized turns/calls to ~/.cache/codeburn/session-cache.json so
the CLI skips re-parsing unchanged JSONL files on subsequent runs.
File reconciliation uses dev+ino+mtime+size fingerprinting; cost,
classification, and summaries are recomputed at query time. Atomic
writes via temp+fsync+rename, deep structural validation on load,
per-provider env fingerprinting, and best-effort save so cache failures
never break the CLI. ~6x speedup on warm cache.
