Summary
Add revisioned state writes, renewable leases, and a SQLite state backend.
The reconciler uses resource leases and compare-and-swap writes to coordinate concurrent mutations. Orphan deletion is serialised through its own lease. The file, memory, and SQLite backends implement the same state contract.
Every mutation must provide the revision it observed. Revision
0asserts that the resource does not exist. SQLite stores resources and their leases in theresourcesandresource_leasestables.Stack
Depends on #26. The PR base points at that branch so this diff contains only state and concurrency work.
