refactor(ci): split CI workflow and optimize path filtering

[Boshen]

Summary

This PR refactors the CI workflow by splitting jobs that use path filtering into separate workflow files and optimizing the use of path filters.

Goal is to reduce total number of CI jobs.

Changes

1. Split CI workflow into multiple files

Moved jobs using dorny/paths-filter to dedicated workflow files:

• test-wasm32.yml - WASM32 testing
• test-napi.yml - NAPI testing
• conformance.yml - Conformance testing
• minification.yml - Minification size checks
• allocations.yml - Memory allocation checks
• ast-changes.yml - AST code generation checks
• linter-codegen.yml - Linter code generation checks

2. Optimized path filtering approach

• Native GitHub path filters (with YAML anchors): Used for workflows with positive path patterns:

  • minification.yml
  • allocations.yml
  • linter-codegen.yml

• dorny/paths-filter: Kept for workflows that require it:

  • test-wasm32.yml - Uses negative patterns (exclusions)
  • test-napi.yml - Uses negative patterns with predicate-quantifier
  • ast-changes.yml - References external YAML file for paths

• No path filters:

  • conformance.yml - Uses complex negative patterns, runs on all changes

Benefits

• ✅ Better organization: Each workflow has a clear, focused purpose
• ✅ Improved maintainability: Smaller, more manageable workflow files
• ✅ Optimized performance: Native path filters are faster where applicable
• ✅ Reduced dependencies: Less reliance on external actions where possible
• ✅ DRY principle: YAML anchors prevent duplication within workflows

Testing

All workflows have been tested with their respective path filtering configurations. The split maintains the same functionality while improving code organization.

Pull Request Overview

This PR refactors the CI workflow by splitting path-filtered jobs into separate workflow files and optimizing path filtering approaches to improve organization and maintainability.

• Extracted path-filtered jobs from the main CI workflow into dedicated workflow files
• Optimized path filtering by using native GitHub path filters with YAML anchors where possible
• Maintained dorny/paths-filter only where complex patterns or external file references are required
