RESULT: SUCCESS

FILES CHANGED:
- internal/toml/decode.go

SUMMARY:
Implemented standard tables, implicit/nested table resolution, array-of-table contexts, dotted-key provenance, and inline-table closure enforcement. Added focused tests.

Scoped suites passed:
- Tables: 24 valid, 62 invalid
- Inline tables: 17 valid, 28 invalid
- Go tests passed

BLOCKERS:
- Full suite retains unrelated pre-existing failures in multiline strings, numeric validation, and integer-sign handling.
