Updates the project to use ESM modules and replaces ncc with esbuild. This fixes build failures caused by newer @actions/core versions which use strict ESM exports that ncc cannot resolve.
Also updates tests to use ESM and dependency injection.

Added comprehensive test cases to achieve near-perfect test coverage:
## Coverage Improvements
- **Statements**: 99.65% (from 76.2%)
- **Branches**: 81.06% (from 55.02%)
- **Functions**: 100% (from 78.57%)
- **Lines**: 99.64% (from 76.97%)
## New Test Files
- `test/summary.test.js`: Complete test suite for summary generation
- `test/index-main.test.js`: Test for main module execution
## Enhanced Test Cases
- Added tests for large output truncation
- Added tests for OSV details with CVE aliases
- Added tests for vulnerabilities without OSV IDs
- Added tests for fixed version recommendations
- Added tests for module call sites and suggested edits
- Added tests for multi-line JSON parsing
- Added tests for error handling edge cases
The only remaining uncovered line is the main module execution check,
which is inherently difficult to test in a unit testing environment.
