fix: fix and improve test isolation and collision with environment (#530)
* 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).

// Tests for durable-source monotonic cost behaviour (PR #477 / copilot-otel).
// Five scenarios:
// (a) file-purge monotonic — copilot JSONL file deleted → total unchanged
// (b) OTel-prune monotonic — OTel DB rows pruned → total unchanged
// (c) no double-count — same source parsed twice → counted once
// (d) non-durable evicts — deleted source for non-durable provider IS removed
// (e) 90-day age-out — orphan ≥ 91d old is pruned; ≤ 89d is retained
