Add durable Yieldstar reconciliation

[djgrant]

Summary

• upgrade the reconciler integration to Yieldstar 0.5.0 and add a host-composable durable reconciliation generator
• store each live resource in a real Yieldstar store, with absence represented by no store and conditional update/delete governed by the runtime UUIDv7 instance identity and version
• serialize concurrent deployments with durable store waiting and preserve completed provider calls across process replay
• convert the Node.js reconciler example and replace the superseded embedded-execution documentation

Verification

• pnpm build — 13 tasks passed
• pnpm typecheck — 11 tasks passed
• pnpm test:once — 107 passed, 4 skipped
• focused reconciler and example tests — 41 passed

The new Node SQLite integration tests cover durable provider retry, crash/resume without repeating a completed create, conditional persistence and stale-instance deletion, and concurrent deployment coordination.

Next stacked phase

• move CLI deploy and destroy onto a resident Yieldstar workflow runtime
• add durable destroy as a first-class workflow operation
• fan independent resources into coordinated child executions while retaining dependency ordering
• connect workflow status and wake state to CLI and dashboard observability

Superseded by the squashed two-PR stack: #42 (reconciliation foundation) and #43 (runtime and CLI cutover). The combined result of that stack is byte-identical to this stack's final tree.
