[Feature Request] Auto-expand relative paths to absolute for terminal clickability

Bug Description
Feature Request: Auto-expand relative paths to absolute for terminal clickability

Summary
When Claude outputs file paths in responses, relative paths (e.g.,
docs/rfcs/001-variant-metafields.md) are not clickable in the terminal, while absolute paths
are. Claude should automatically output absolute paths to improve UX.

Current Behavior
Created RFC at docs/rfcs/001-variant-metafields.md
→ Not clickable in terminal

Expected Behavior
Created RFC at
/Users/kromann/dev/taxon-agents/taxon-barefoot-aps/docs/rfcs/001-variant-metafields.md
→ Clickable, opens in IDE

Why This Matters

• Modern terminals (iTerm2, Wezterm, Ghostty, VS Code integrated terminal) support clickable

file paths

• Cursor and VS Code terminals make absolute paths clickable, allowing quick navigation
• Claude knows the working directory, so expanding paths is trivial
• Reduces friction when Claude references files in output

Suggested Implementation

1. When outputting a file path that exists, expand to absolute path
2. Alternatively, use file:// URI format
3. Could be a setting: "Output absolute paths" (default: on)

Workaround
User can ask Claude to use absolute paths, but this shouldn't require explicit instruction.
