Windows: add timestamps and ANSI/severity colors to Run output

[1lck]

Summary

The Windows Run pane renders child-process output as one plain foreground-colored <pre> block and does not add timestamps. Maven and other tools launched through piped stdio, especially in batch mode, often emit no ANSI styling, so [INFO], [WARNING], and [ERROR] lines all appear as white text.

macOS already provides the expected behavior through OutputTextView and OutputTimestamper: ANSI rendering, severity-based fallback colors, and leading timestamps.

Current Windows behavior

• run-output events contain only sessionId and a raw text chunk.
• run.store.ts concatenates chunks into a plain string.
• run-pane.tsx displays the string directly in a fixed-color <pre>.
• There is no timestamping or ANSI parser in the Windows Run feature.
• Piped Maven output such as mvn.cmd -B -ntp spring-boot:run therefore renders as an undifferentiated wall of text.

Relevant code:

• windows/tauri/src-tauri/src/run.rs
• windows/tauri/src/features/run/hooks/use-run-process-events.ts
• windows/tauri/src/features/run/stores/run.store.ts
• windows/tauri/src/features/run/components/run-pane.tsx
• macOS reference: macos/Sources/Lithe/Views/Workbench/OutputTextView.swift

Expected behavior

1. Prefix each new logical output line with a local timestamp while preserving chunks that continue an existing line.
2. Parse and render ANSI styles when the process provides them; do not show raw escape sequences.
3. When no ANSI styling is present, color lines by stable severity tokens such as ERROR, WARNING/WARN, INFO, and DEBUG/TRACE.
4. Dim timestamps so they remain readable without competing with the message.
5. Preserve existing UTF-8/Windows code-page decoding, output-size trimming, stdout/stderr streaming, stdin support, and session isolation.
6. Add focused tests for split chunks, partial lines, ANSI reset sequences, severity fallback, and timestamp continuation behavior.

Reproduction

1. Open a Maven/Spring Boot run configuration on Windows.
2. Run it and inspect output containing [INFO], [WARNING], and [ERROR] lines.
3. Observe that every line uses the same foreground color and has no timestamp.
