Build summary

RESULT: SUCCESS

FILES CHANGED:

• internal/toml/decode.go
• internal/toml/value_test.go

SUMMARY: Implemented strict TOML numeric, boolean, and datetime lexing with lossless int64 handling, special floats, separators, fractional truncation, and validation. All declared acceptance slices, tests, and go vet pass.

BLOCKERS:

• Full suite still has failures in out-of-scope key, table, string, and inline-table behavior.
