pakka v0.8.0
User edit preservation release.
Fixes silent data loss when a user edits a live compressed file (CLAUDE.md, DESIGN.md) then changes the compression level. Previously the orchestrator would silently overwrite those edits with re-compressed stale content.
Fix: orchestrator now records the SHA of each compression output (OutputSHA). On subsequent runs, if the live file differs from the last output SHA, user edits are detected and adopted as the new baseline before re-compressing. Snapshot write failures abort the pass rather than overwriting user edits.
All 19 orchestrator tests pass including 3 new behavioral tests.
