fix: address 4 medium-priority findings (PERF-005/007, CI-001, TEST-005)

[laurentiu021]

PERF-005: ConsoleViewModel O(n) trim fix. PERF-007: ProcessManager icon extraction off UI thread. CI-001: auto-release handles breaking changes (major bump). TEST-005: UI test failure annotations. Build: 0 errors.

Summary by CodeRabbit

• Bug Fixes

  • Fixed semantic versioning to properly classify breaking-change commits as major version bumps.
  • Improved process manager responsiveness by performing process enrichment on a background thread.
  • Performance optimizations for console output and regex operations.

• Improvements

  • Enhanced CI failure visibility with inline notifications for test failures.

📝 Walkthrough

Walkthrough

This PR bundles v0.50.0 release changes: workflow updates enable proper semantic versioning for breaking-change commits and visible CI test failures; ViewModels receive performance optimizations for console line trimming and background process enrichment; release notes document all changes.

Changes

v0.50.0 Release: Infrastructure and Performance Improvements

Layer / File(s)	Summary
Auto-release major version bump for breaking changes .github/workflows/auto-release.yml	Commit patterns feat(...)!: and fix(...)!: now trigger major version bumps; version calculation explicitly increments MAJOR and resets MINOR/PATCH to 0.
CI UI test failure warning annotations .github/workflows/ci.yml	UI test step now carries an explicit id and workflow emits a PR warning annotation when the UI test step fails, improving failure visibility.
Console line trim performance optimization SysManager/SysManager/ViewModels/ConsoleViewModel.cs	Excess line removal now uses a forward loop removing from index 0, replacing backward iteration for improved trim efficiency when Lines exceed MaxLines.
Process enrichment background threading SysManager/SysManager/ViewModels/ProcessManagerViewModel.cs	Process icon extraction and description/category/safety lookup moved to background Task.Run; Processes collection cleared and repopulated on completion to avoid main thread blocking.
Release notes documentation CHANGELOG.md	v0.50.0 release entry documents all performance and infrastructure fixes dated 2026-05-13.

🐰 Workflows bump majors for breaking change cheer,
Threads spin processes off to the rear,
Consoles trim lines with a forward-loop sweep,
CI warns boldly when tests fail so deep,
Release v0.50.0 hops into view!

⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Correct the complexity claim wording.

Line 12 says this change “fix[es] O(n²),” but removing from index 0 repeatedly is still O(n) per removal and can still be quadratic for larger trims. Please adjust the release note to describe the behavioral fix (oldest-first trimming) without claiming an O(n²) elimination.

Suggested wording

-- **Performance: ConsoleViewModel** — fix O(n²) trim by removing from index 0
-  forward instead of reverse-order removal (PERF-005).
+- **Performance: ConsoleViewModel** — fix trim order to remove oldest lines
+  first (index 0), preserving the most recent output (PERF-005).

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	- **Performance: ConsoleViewModel** — fix O(n²) trim by removing from index 0
	forward instead of reverse-order removal (PERF-005).
	- **Performance: ConsoleViewModel** — fix trim order to remove oldest lines
	first (index 0), preserving the most recent output (PERF-005).
