feat: Zig 0.15 compat, e2e smoke tests, VeriSimDB quadlet, build improvements

- Update all FFI modules for Zig 0.15.2 compatibility:
  - Add `pub` to all `export fn` declarations (module visibility)
  - Migrate VeriSimDB HTTP client from open/send/wait to fetch() API
  - Use std.Io.Writer.Allocating for response body collection
  - Fix JSON array detection to not misclassify TOML [[tables]]
  - Replace std.json.stringify with placeholder for array values
- Add -Dgossamer-lib-path build option for optional Gossamer linking
- Add `registerFromText` to ProfileRegistry for in-memory profile loading
- Fix A2ML attribute parser to handle unquoted numeric values
- Use build module imports for tests (fixes Zig 0.15 import path rules)
- Add e2e smoke test suite (test-smoke): full pipeline without live services
- Add VeriSimDB Podman quadlet (gsa-verisimdb.container)
- Activate .tool-versions (rust nightly, zig 0.15.2, idris2 0.7.0, just 1.40.0)
- Update .gitignore (track .tool-versions, ignore test_managed/)
- Update STATE.a2ml: 82% completion, B1 resolved, session logged
- Update EXPLAINME.adoc: clarify normalizer stubs are in VeriSimDB repo

All 3 test suites pass: unit, integration (36 tests), smoke.
