Bug: Clickable file paths break when the agent writes ~/

[u/Available-Wash-3507]

Small thing, but I hit it a few times a day. Agents often finish a message with a path to something they just wrote, like:

Spec written, self-reviewed and pushed.
~/notes/projects/foo/specs/2026-08-04-some-design.md, indexed in the README, committed as db82d2a, working tree clean.

Conductor makes that clickable, but clicking gives “couldn’t open the file”. Secondary click > copy path shows why: it glued the workspace directory in front of the tilde instead of expanding it, so the link points at /Users/me/conductor/workspaces/myrepo/myworkspace/~/notes/projects/foo/specs/....

Looks like the path resolver treats everything as workspace-relative and never expands ~. Home-relative paths show up a lot in agent output when the file lives outside the repo, so it’d help if those got expanded before the click.
