fix(vscode): keep HTTP status with error title

[marius-kilocode]

Tool errors currently treat the HTTP status and status text as one flexible message. In constrained sidebar layouts, that can place the status code away from the error title or split the status text mid-word, making errors such as GitHub API error: 401 Unauthorized difficult to scan.

This keeps a leading three-digit HTTP status grouped with the structured error title while allowing the descriptive status text to wrap independently. General tool errors retain their existing title/detail treatment, and very narrow layouts prioritize readable text over the decorative error icon.

The composite webview stories now cover both an HTTP error and a filesystem error at standard and narrow sidebar widths so future layout changes preserve the intended grouping and wrapping behavior.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

The implementation is correct across all three commits. The HTTP status regex (/^(\d{3})(?:\s+|$)/) cleanly extracts the three-digit code from message, and message.slice(code.length).trimStart() handles the trailing space correctly. The message-part-tool-error-heading wrapper with flex: none; white-space: nowrap achieves the intended grouping.

The follow-up fix(ui): align tool error text baselines commit correctly hoists shared font properties (font-family, font-size, font-style, line-height, letter-spacing) to the parent message-part-tool-error-content container and adds align-items: baseline to both the content container and the heading wrapper — a clean refactor with no duplication or regressions.
