feat(s3): extract typed_wasm engine + route 39 disciplines through TypeInfo

The TypedWasm prover oracle is now a standalone crate at crates/typed_wasm
with zero echidna-core dependencies. The pure parse/analyse engine is
parametrised by a TypeInfo value, so the 39 *TypeChecker variants all
route through one backend with discipline-specific active-level sets,
replacing the catch-all HPEcosystemBackend route.

- crates/typed_wasm/src/lib.rs: pure engine (parse + obligation generation
  + TypeInfo + analyse). 9 crate-level tests covering the level-filter
  semantics and the discipline-aware analysis flow.
- Cargo.toml: crates/typed_wasm added to [workspace].members; typed-wasm
  added as a path dependency.
- src/rust/provers/typed_wasm.rs: rewritten as a thin adapter that maps
  typed_wasm::Analysis onto echidna's core ProofState/Goal types. Adds
  TypedWasmBackend::with_type_info and ::for_kind constructors, plus a
  type_info_for(kind) helper that maps each *TypeChecker variant to its
  discipline's active safety-level set (linear, affine, modal, temporal,
  refinement, session, …). TypedWasmBackend::new preserved for the legacy
  full-oracle callers.
- src/rust/provers/mod.rs: ProverFactory::create now routes the 39
  *TypeChecker variants through TypedWasmBackend::for_kind. TypeLL and
  KatagoriaVerifier continue to dispatch through HPEcosystemBackend as
  genuine HP upstream binaries.

Tests: 9/9 crate + 10/10 adapter + 625/625 echidna lib pass.
