- Apply LoadableScalar conversions (masking, sign-ext) for PlaceLoad
- Add defensive fallbacks for empty/missing field type info
- Fix merge_block return consistency for terminating arms
- Remove debug prints, add proper error handling for missing body
- Include variant index in hash_place for dedup safety

- Convert defensive fallbacks in lower_place_address to hard YulError
  failures for any field_types query returning empty or out-of-bounds
- Error on target field access when field doesn't exist in type info
- Include enum_ty in hash_place via pretty_print to preserve type
  system semantics during MIR function deduplication
- Improve comment for Absent patterns explaining the design decision

- Add generic Projection/ProjectionPath types with Infallible for HIR index slots
- Refactor match lowering to use Place with projections (defer offsets to codegen)
- Extract shared layout module eliminating duplicate ty_size_bytes implementations
- Inline field loads in codegen, removing helper function indirection

Trust decision tree's default block rather than rediscovering wildcard arms.
This fixes Outer::First(_) patterns being incorrectly routed to top-level wildcards.
