Console output filters for clickable file paths

[nam-hle]

Summary

Add console filters that make file paths and stack traces in nadle task output clickable, navigating directly to the source location.

Motivation

When a task fails, users see file paths and stack traces in the console. Making these clickable saves time and matches the behavior of other IDE-integrated tools.

Acceptance Criteria

• File paths in task output are hyperlinked to the editor
• Stack trace lines (e.g., at foo (/path/file.ts:10:5)) are clickable
• Relative paths resolved against working directory
• Works for both Run and Debug console output

Implementation Notes

• Implement ConsoleFilterProvider or Filter for the execution console
• Register via <consoleFilterProvider> extension point
• Use OpenFileHyperlinkInfo for navigation
• Pattern match common formats: Node.js stack traces, TypeScript paths, ESLint output
