Restore the fresh-palace dry-run regression alongside the existing-empty
and initialized-sqlite_exact cases. Cover explicit failure for unsupported
adapter result types and daemon source-adapter dispatch. Ignore Hypothesis'
test cache so it cannot be committed.
- existing-uninitialized palace dir dry run: assert no chroma.sqlite3
- initialized sqlite_exact palace dry run: assert artifacts byte-identical
- replace mocked MineAlreadyRunning CLI test with a real held writer lease
