Summary

• Register toml
• Highlight comments, bare, quoted, and dotted keys, standard and array-of-tables headers, basic, literal, and multiline strings, integers in supported bases, floats and special float values, booleans, offset and local date-time values, arrays, inline tables, separators, and delimiters
• Add focused tests and a benchmark fixture

This is a clean resubmission of the closed #227, based directly on main: no core changes and no visual test harness.

Verification

• vendor/bin/php-cs-fixer fix --allow-risky=yes — no remaining changes
• vendor/bin/phpstan analyse src tests — no errors
• vendor/bin/phpunit — 865 tests, 1,170 assertions
• vendor/bin/phpbench run tests/Bench/HighlighterBench.php --variant='^toml$' --report=aggregate — 100.64 μs (±0.54%)

Can you add pattern tests please? Look at any other language pattern to see how they work.

Sorry for the double review

[eas4ai]

Added #[PatternTest] attributes to all 8 TOML pattern classes.

Verified locally before pushing: vendor/bin/phpunit — 881 tests, 1,186 assertions; vendor/bin/phpstan analyse src tests — no errors; PHP-CS-Fixer clean.

[eas4ai]

Rebased onto current main to resolve the conflicts in src/Highlighter.php and tests/Bench/HighlighterBench.php after the recent language merges. The TOML changes and pattern tests are unchanged apart from fitting the updated registration and benchmark lists.

Verified locally after the rebase: vendor/bin/phpunit — 1177 tests, 1739 assertions; PHPStan reports no errors. GitHub now reports this PR as mergeable with all checks passing.
