0.1.1

Professional Hardening and Control Signals

Added

• Public SerialControlSignals model for RTS, CTS, DTR, DSR and DCD status snapshots.
• SerialPort.getControlSignals() and SerialPort.getCts() APIs.
• Linux MethodChannel support for reading control signals and setting DTR/RTS through the existing native getControlSignals and setControlSignals handlers.
• Windows FFI support for reading CTS/DSR/DCD status and tracked DTR/RTS output state.
• 100% line-coverage gate for the configured test coverage scope.
• Professional GitFlow branch-protection ruleset, release manager agent, Copilot quality gate skill, repository templates and cross-platform development setup scripts.

Changed

• Release publishing now targets pub.dev trusted publishing/OIDC and creates GitHub tags/releases only after successful publish.
• Documentation now includes Mermaid diagrams for architecture, quality gate, GitFlow and release workflows.

Verified

• flutter analyze --fatal-infos --fatal-warnings
• flutter test --coverage
• dart run tool/coverage_gate.dart --lcov coverage/lcov.info --min-lines 100
• flutter pub publish --dry-run
