RESULT: SUCCESS

FILES CHANGED:
- internal/toml/decode.go
- internal/toml/value_test.go

SUMMARY:
Implemented TOML comment handling in multiline values, CRLF normalization, continuation support, UTF-8/control-character validation, TOML whitespace enforcement, and quoted-key parsing.

Acceptance slices pass: comments 7/7, controls 32/32, encoding 14/14.

BLOCKERS:
- Full suite retains unrelated pre-existing failures in tables, numeric strictness, inline tables, and key semantics.
