Pull request overview
This PR adds coverage failure-threshold support to the coverlet.MTP extension, aligning it with existing threshold behavior in other Coverlet drivers, and updates the MTP integration documentation and tests accordingly.
Changes:
- Introduces threshold settings (
Threshold,ThresholdType,ThresholdStat) in MTP settings/config parsing and exposes them via command-line options. - Adds threshold evaluation/output in the collector and sets a non-zero exit code when thresholds are not met.
- Updates MTP docs and adds/extends unit tests around parsing/validation and threshold reporting.

- Add CoverletCoverageDataProducer for MTP message creation/publishing - CollectorExtension now publishes coverage, threshold, and report messages to IMessageBus - Refactor exit code logic for threshold failures - Update CollectorExtensionProvider for DI of message bus and producer - Refactor and add tests for message-based reporting and producer logic - Update integration test for new summary output - Bump MicrosoftTestingPlatformVersion to 2.4.0 - Update .github/copilot-instructions.md for test/code standards and netstandard2.0 rules
The code now computes and reports method coverage alongside line and branch coverage. It introduces overall and per-module method coverage metrics using CoverageSummary.CalculateMethodCoverage, and includes these in the TestCoverageMessage output. Method coverage is now always calculated and reported, independent of threshold configuration.
