Merged 10 upstream commits (MemTable, read-your-writes tests, feed endpoint,
security hardening, signed assertions, source registry, dashboard enhancements)
and fixed all test failures across the full workspace (2656/2656 passing).
Key fixes:
- fix(cluster): DashMap deadlock in swim.rs suspect_node/fail_node/alive_node
- DashMap::get_mut RefMut + iter() on same map = non-reentrant write lock deadlock
- Fix: extract clone in scoped block to drop RefMut before calling update_node_gauges()
- 6 previously-hanging SWIM tests now pass in <2s
- fix(sim): replace background-task+polling ingestion with synchronous process_pending()
- smoke_high_volume_simulation was CPU-starved under 2656 parallel tests
- Removed ingestor.start() + wait_until_ingested() pattern throughout sim
- All arena functions now call ingestor.process_pending() directly (deterministic)
- fix(test): v2 signature helper used wrong hash (rkyv vs canonical compute_content_hash_v2)
- fix(test): quota test signed "test" but v1 requires "subject:predicate" format
- fix(test): http_validation now accepts 400 for valid-format-but-invalid-crypto hex
- fix(test): scale_adaptive micro tier assertions updated (auto_promote upstream change)
- config: add nextest.toml with slow-timeout for background-task-tests group

- Add Layered() method to Go SDK for per-source-class consensus queries
- Add LayeredQueryParams, LayeredResult, TierResolution types to Go SDK
- Create conflict example demonstrating Skeptic and Layered endpoints
- Update quickstart.md with sections 6 (conflict detection) and 7 (authority tiers)
- Remove tracked Go binary and add data/ to .gitignore
The new quickstart sections demonstrate Episteme's differentiating features:
- Skeptic endpoint shows "Trust but Verify" conflict analysis
- Layered endpoint shows per-tier resolution (Clinical vs Anecdotal)
Note: Pre-existing large files flagged by pre-commit hook (technical debt from prior sessions)
