[BUG] Clickable file-path links resolve against the wrong base dir (repo subfolder, not the session cwd) → file-not-found on click

What's Wrong?

When the working directory is a parent of the project I'm asking about,
Claude renders a file reference as a clickable markdown link but emits the path
relative to the project/repo subfolder, not relative to the session
working directory. The link therefore resolves to a path that doesn't exist,
and clicking it fails (file not found / nothing opens).

Example from a real session — cwd was C:\Users\<me>, the repo lived at
C:\Users\<me>\hermes-agent\:

• Claude wrote a link to agent/foo.py
• The client resolved it against the cwd → C:\Users\<me>\agent\foo.py (does not exist) → click fails
• The correct, clickable path would have been hermes-agent/agent/foo.py

This is distinct from the existing clickability issues:

• #69645 — backtick/plain-text paths not clickable at all
• #90336 — links with spaces/umlauts not found
• #88936 (closed) — absolute-path links render but don't resolve (so "just use absolute paths" is already known not to work)

Here the link IS clickable and the format is fine — the base directory used
to resolve the relative path is wrong.

What Should Happen?

What Should Happen?

A relative file-path link should resolve against (and be emitted relative to)
the session working directory, so it is clickable regardless of whether the
file lives in a subfolder of the cwd. At minimum, clicking a rendered file link
should open the file when that file exists on disk under the cwd tree.

Steps to Reproduce

Steps to Reproduce

1. Start Claude Code with the working directory set to a folder that contains

a git repo as a subfolder (e.g. cwd = C:\Users\me, repo at
C:\Users\me\myrepo).

1. Ask Claude about a file inside the subfolder repo (e.g. "what does

myrepo/src/app.py do?").

1. Claude replies with a clickable link whose href is src/app.py

(relative to the repo), not myrepo/src/app.py (relative to cwd).

1. Click the link.

Result: file-not-found / nothing opens (the path resolves to
C:\Users\me\src\app.py, which doesn't exist).
Expected: the link opens C:\Users\me\myrepo\src\app.py.
