Description

This PR fixes an issue where glob patterns with leading ./ prefixes (like ./packages/*) were not being consistently handled in workspace filtering and glob matching throughout Turborepo.

Problem:

• Workspace globs like ./packages/* and packages/* should be functionally equivalent
• The current implementation didn't normalize these patterns, causing inconsistencies in package filtering
• This led to scenarios where turbo run build --filter="./packages/*" might not match the same packages as turbo run build --filter="packages/*"

Solution:

• Normalize leading ./ patterns in fix_glob_pattern: Strip the ./ prefix from glob patterns during normalization while preserving ../ patterns (which have different semantic meaning)
• Enhanced filtering compatibility: Update the package filtering logic to handle both original and normalized patterns, ensuring compatibility with workspace globs that might have or lack the ./ prefix
• Comprehensive test coverage: Add test cases to validate that ./packages/* and packages/* produce identical results

Key Changes:

1. crates/turborepo-globwalk/src/lib.rs: Modified fix_glob_pattern() to normalize leading ./ patterns
2. crates/turborepo-lib/src/run/scope/filter.rs: Enhanced filtering logic to try both original and normalized patterns
3. crates/turborepo-repository/src/inference.rs: Fixed test assertions for repo state inference

Examples of patterns affected:

• ./packages/* → packages/*
• ./packages/** → packages/**
• ../packages/* → ../packages/* (preserved - different semantic meaning)

This ensures consistent behavior across all workspace filtering operations and improves the developer experience by making glob patterns more predictable.

Testing Instructions

1. Basic functionality test:

   # Both of these should now match identical packages
   turbo run build --filter="./packages/*"
   turbo run build --filter="packages/*"

2. Run the test suite:

   cargo test test_fix_glob_pattern
   cargo test test_leading_dot_slash_pattern_normalization

3. Test workspace filtering:

   # In a monorepo with packages in a `packages/` directory
   turbo run build --filter="./packages/*" --dry-run
   turbo run build --filter="packages/*" --dry-run
   # Output should be identical

4. Verify edge cases:

   # Should preserve ../ patterns (different semantic meaning)
   turbo run build --filter="../packages/*" --dry-run
