docs: add Temporal architectural analysis
8,958 commits, 290 contributors, heavyweight Go infrastructure.
Key findings:
- HSM framework: type-safe state transitions, source validation
- CHASM: mutable vs immutable contexts enforced at type level
- goro.Handle: predates CockroachDB's Handle by 3.5 years (same solution)
- softassert: production assertions that log, don't crash
- 566 dynamic config settings with namespace-scoped resolution
- uber/fx for DI (justified by genuine service graph complexity)
- Domain error types → gRPC mapping (not generic wrapping)
PR discussions show:
- HSM (#5494): 'not final, step in the right direction' — explicit iteration
- CHASM (#6987): separate contexts to make mutation impossible in read paths
- goro.Handle (#1892): born from double-close panic, reviewer rule: 'if expert asks, code needs comment'
