Maintainer follow-up:
- Derive JetBrains dedup keys from the reply content (sha256 prefix plus a
per-hash occurrence counter) instead of the blob's scan position. Copilot
is a durable provider: cached turns are never deleted and a re-parse
appends any unseen key, while MVStore compaction can rewrite the store
with blobs in a different byte order. With positional keys, a rewrite
that moves a new blob ahead of an old one hands the new turn the old
key (skipped as seen) and re-emits the old turn under a fresh index,
double-billing it. Covered by a regression test that fails on the
positional scheme.
- Add CODEBURN_COPILOT_JETBRAINS_DIR to the env-isolation cleared list so
a developer's real JetBrains store never bleeds into fixture tests.
* fix: fix and improve test isolation and collision with environment
* docs: remove unnecessary comment
* test(env-isolation): clear CODEBURN_FORCE_MACOS_MAJOR and pin TZ
Two env vars read in src/ were not isolated: CODEBURN_FORCE_MACOS_MAJOR
(now cleared so it cannot leak between tests) and TZ (now pinned to UTC,
since clearing it falls back to the OS zone and would shift date buckets
versus a clean CI runner).
