fix: prevent heap overflow in large monorepo scans

[jdalton]

Summary

• Prevent heap overflow in large monorepo scans by using streaming-based filtering

Changes

• Added createSupportedFilesFilter() function to create filter functions from supported file patterns
• Added filter option to GlobWithGitIgnoreOptions for streaming-based filtering
• Modified globWithGitIgnore() to apply filter during streaming instead of accumulating all files first
• Updated getPackageFilesForScan() to use streaming filter to avoid OOM errors in large monorepos (100k+ files)

Test plan

• Test scanning large monorepos with 100k+ files
• Verify memory usage remains stable during scans
• Ensure file filtering still works correctly

Note

Implements streaming-based file filtering to reduce memory usage during scans and updates dependencies.

• Adds filter option to globWithGitIgnore() and applies it during stream processing (supports negated gitignore patterns)
• Introduces createSupportedFilesFilter() and uses it in getPackageFilesForScan() to filter supported files early
• Keeps existing fast path when no negations or filter are present
• Updates external-tools.json to @coana-tech/cli@14.12.148
• Updates CHANGELOG.md with Unreleased notes for the fix
