📝 Walkthrough

Summary by CodeRabbit

• New Features

  • Added configurable batch processing to the formatting command, with a default batch size of 50 files.
  • Formatting tools now process multiple files in a single operation.
  • Files are grouped by their applicable formatter while preserving formatter order.

• Performance Improvements

  • Reduced repeated formatter launches, making large formatting runs faster and more efficient.

Walkthrough

The format command now collects files, groups them by formatter, and processes configurable batches. Formatters provide batch methods. Biome, ESLint, PHPCBF, Pint, and Stylelint pass multiple files to one formatter process.

Changes

Formatter batching

Layer / File(s)	Summary
Command batch orchestration classes/local/cli/commands/format.php	Adds --batch-size, collects files, groups them by formatter, and invokes format_batch for each batch.
Base batch contract classes/local/format/base.php	Adds format_batch, which delegates each file to the existing format method.
Native formatter batch execution classes/local/format/biome.php, classes/local/format/eslint.php, classes/local/format/phpcbf.php, classes/local/format/pint.php, classes/local/format/stylelint.php	Adds batch execution for each formatter and passes all batch file paths to one formatter process where supported.
