Optimizes `saveMemoryStore` in `src/services/memory/index.js` to use `fs.promises.writeFile` instead of synchronous `fs.writeFileSync`.
Implements a coalescing mechanism to handle concurrent save requests efficiently, preventing race conditions and reducing I/O operations by batching pending updates into a single write.
Reduces event loop blocking from ~420ms (sync) to ~3ms (async) for large write operations in benchmarks.
Updates all `memoryRepository` methods to await the async save operation.

- Use Promise.all to execute memory lifecycle actions concurrently.
- Maintain intra-item dependency order (merged_into before action).
- Update tests to support non-deterministic execution order of independent items.
- Benchmark shows ~65x improvement for 100 items with 10ms latency.

Avoids redundant string concatenation and lowercasing in the inner loop of `buildSimilarityIndex`.
Pre-computes query terms and regexes once per query.
Uses RegExp.test for case-insensitive matching without allocation.
Benchmark shows ~2x speedup (99ms vs 191ms for 10k memories).

Sorts memories by created_at and uses an early exit condition in the inner loop to avoid checking all pairs. This reduces complexity from O(N^2) to roughly O(N * k) where k is the number of items within the duplicate window.
Measured improvement for 30k items: ~2.1s -> ~0.25s (8x speedup).

Moved the `ensureDir` utility function from `src/ops.mjs` to `src/utils.mjs` to promote code reuse and centralization.
Updated `src/ops.mjs` and `src/services/memory/index.js` to use the shared utility.
Added unit tests for `ensureDir` in `test/utils.test.mjs`.

- Modified `getRelevantMemories` in `src/services/memory/index.js` to accept optional `ranker` and `cache` parameters for dependency injection.
- Added `test/memory-index.test.mjs` with comprehensive unit tests for `getRelevantMemories` using `node:test` mocks.
- Verified that existing behavior is preserved via default parameters.

- Update `markMemoryMerged` to accept `options.repository` for better testability.
- Add unit tests in `test/memory-admin.test.mjs` to verify:
- Delegation to repository.
- Cache clearing side effect.

Replaced `console.log` with `util.debuglog('torch-memory')` in `src/services/memory/index.js` to prevent stdout pollution. Telemetry and metrics are now logged to stderr only when `NODE_DEBUG=torch-memory` is set, improving library behavior and observability control.
Added regression test `test/memory-telemetry.test.mjs`.

- Add `test/memory-pinning.test.mjs` to test `pinMemory` happy path and edge cases.
- Update `getRelevantMemories` in `src/services/memory/index.js` to use `repository.listMemories` when available, enabling isolated unit testing.
- Verified all memory tests pass.
