14b4c56e57 feat(chord,durable): Chord v2 slice 6b, Durable and jobs on the store
StoreStorage (Durable's storage on Chord v2's store, @earendil-works/pi-durable/storage/store) passes
Durable's storage conformance suite and runs Durable's harness tests (npm run test:store). The store
gets owner names and claims, one id allocator, Durable's Storage semantics for refused steps, history
none/latest/rewindable with reads at a point, archive revisions and applyBatch. self.follow follows
Durable's synchronous observers as Chord sources. Persisted jobs: records and state in the owner's
store, restarts as Durable's tasks, abort stored, deferred state. Chord's ./next export returns for
the adapter surface.

db14038bd8 fix(chord): bound the Node SQLite driver's prepared-statement cache
The driver kept every statement it ever prepared. It now keeps the 256 most
recently used per connection; below half the limit a hit stays one lookup.

8025c414d1 feat(chord): SqliteExecutor.runCounted resolves with the rows a statement changed
The Node driver takes the count from node:sqlite; the Durable Object driver reads
SELECT changes() after the statement, since the cursor's rowsWritten also counts
index writes (verified in workerd). run is unchanged and costs nothing more.

89e309581b fix(chord): remove WAL page replication
Reverts 48c8f3228 and 4759f09fb. Session sync replicates pi-durable commits instead of SQLite pages, so NodeSqliteDatabase.exclusive(), the replicated connection wrapper, the WAL reader, page checksums, the segment container, start-marker keys and the zstd page compressor have no user.

48c8f32284 feat(chord): exclusive SQLite operations and a replicated connection wrapper
NodeSqliteDatabase.exclusive() runs an operation alone on the connection, outside a transaction, and rolls back a transaction the operation left open.

The internal replicated connection wrapper opens a database file with automatic checkpoints off, reports every operation, and runs a hook before SQLite checkpoints and deletes the WAL on close. It is not exported from the package yet.
