📝 Walkthrough

Walkthrough

This PR adds monorepo support by introducing a subdirectory action input. When separate jobs target different subdirectories, their coverage uploads are consolidated into a single commit status with aggregated totals. The implementation includes documentation, type definition updates, and changes to the commit status URL structure.

Changes

Cohort / File(s)	Summary
Documentation README.md	Adds subdirectory input documentation and new "Monorepo support" section explaining how separate uploads per subdirectory are consolidated into a single commit status with summed coverage totals.
Type Definition src/post-coverage.ts	Expands CoverageResponse type with repository_id: string property to support new URL construction.
Payload and URL Configuration src/main.ts	Includes subdirectory field in the postCoverage payload (normalized to null if empty) and updates patch coverage commit status target_url to use repository_id and sha instead of id.
