v2.0.2

# SpacetimeDB v2.0.2

A bug fix and quality-of-life release following the 2.0 launch. This release focuses on CLI improvements, durability tuning, and documentation fixes.

## Bug fixes

- **TypeScript: fix table schema wire name lookup crash.** The TypeScript SDK was using PascalCase accessor names for wire protocol lookups, causing crashes when case conversion was enabled. (#4449)
- **`spacetime dev`: fix file watcher ignoring `--module-path`.** When `--module-path` was set via CLI flag or `spacetime.json`, the file watcher still watched the default directory instead. (#4464)
- **`spacetime dev`: better error when module directory does not exist.** Previously showed a confusing "could not detect language" error. Now shows the actual missing path. (#4467)
- **Fix "Press any key to exit" in templates.** The prompt said "any key" but actually required Enter. Updated text and logic to match. (#4468)
- **Don't save `source_config` to `spacetime.json`.** Internal build configuration was being persisted to the user-facing config file. (#4422, #4423)

## Performance

- **Reduce local durability fsync interval to 10ms** (down from misconfigured 500ms default), improving confirmed reads latency for local (non-replicated) databases. (#4466, #4420)
- **C# SDK: `ArrayPool` for row iteration buffers.** `RawTableIterBase.Enumerator` now rents from `ArrayPool<byte>.Shared` instead of allocating a fresh `byte[]` per step, significantly reducing GC pressure. (#4385)

## Documentation

- Correct unique indexes in cheat sheet to use `filter`, not `find`. (#4452)
- Correct "table" to "view" in Zen of SpacetimeDB. (#4434)
- Update C# docs with `List<T>` returns and `IEnumerable<T>` examples. (#4392)
- Fix AI assistant rules links in `llms.txt`. (#4430)
- Add ARM M-series CPU note in benchmark readme. (#4426)
- Add schedule name correction for LLM rules. (#4370)
- Fix Spacerace button and rename nav item to Referrals. (#4458, #4477)
