What issue are you seeing?

Markdown links to local files in assistant chat output render as
non-clickable text — clicking does nothing. External https:// links in the
same messages are clickable and open correctly, so markdown rendering
itself works; only local-file targets are dead.

Example emitted by the assistant (a documented pattern in our project skills):

[L1 — line 33](/home/dev/workspace/project/file.md:33)

renders as non-actionable text: no hover target, no click behaviour.

What steps can reproduce the bug?

1. In the VS Code extension (v0.6.4), ask the agent to review a file and cite
   findings as markdown links with absolute paths and :line suffixes, e.g.
   [L1 — line 33](/home/dev/workspace/project/file.md:33).
2. Click the link in the chat view. Nothing happens.
3. Control: an https:// link (e.g. a GitHub issue URL) in the same message
   clicks through normally.

Variants tested — all dead (same target file, one per message):

• absolute path with :line
• absolute path without :line
• file:///abs/path, with and without :line
• workspace-relative path with :line
• vscode://file/abs/path:line
• bare /abs/path:line as plain text (no markdown)
• label variants: em-dash, ASCII hyphen, no separator (label parsing ruled out)

What is the expected behavior?

Clicking a markdown link to a local file opens that file in the editor,
ideally at the line given by the :line suffix — the behaviour other
coding-agent extensions provide for file:line references in chat output.

Additional information

• The https-vs-file asymmetry within a single message reproduces cleanly
  and is the sharpest evidence.
• Agentic editing workflows that cite findings as file:line links lose
  their navigation affordance; every reference must be opened by hand.
• Tracker searched before filing: nearest item is #2051 (TUI URLs in
  terminal output, enhancement) — not the same. No existing issue covers
  file links in the extension chat view.

Start in the VS Code extension's chat-view markdown-link handling and reproduce the reported local-file cases alongside an https link. Trace how local targets are parsed and dispatched; done means absolute, workspace-relative, file://, and file:line links become clickable and open the file, ideally at the requested line, without regressing external links.
