chore: remove BMAD framework files and IDE configuration artifacts

Clean up unused BMAD workflow, agent, and command files across all IDE
configurations (.agent, .clinerules, .cursor, .gemini, .github, .kilocode,
.opencode) and internal module files (_bmad/bmb, _bmad/bmm).

 - Hashed the snapshot with `sha2::Sha256` to create `input_hash`.
 - Embedded `SimulationMetadata` inside `ConvergedState` results.
 - Added deterministic hashing tests and integration test.
+- **Code review 2026-03-15**: Sorted thermal couplings in `generate_canonical_bytes` for cross-run determinism; documented `fluid_backend_version` placeholder; added `SimulationMetadata::to_json()`; fixed story typo; added test for same topology / different fluid → different hash. File List: `crates/components/src/lib.rs` is listed because `Component::signature()` (used in canonical bytes) is defined in that crate.
 
 ### Change Log
 - **2026-02-22**: Implemented traceability metadata for solver outputs (Tasks 1-4).
+- **2026-03-15**: Code review fixes (determinism, docs, JSON helper, tests).
