* feat(app): link #123 issue and pull request references in Markdown
Agents cite issues and pull requests by number; reading one meant looking
up the URL by hand. Markdown in a workspace now links forge shorthand
against the workspace's origin remote: `#N`, GitLab and Gitea `!N`, and
cross-repository `owner/repo#N` on the same host.
Each forge's URL grammar declares which sigil maps to which path, so the
syntax stays per forge: GitHub has no `!`, and its `#` targets /issues/,
which GitHub redirects to the pull request. Recognition goes through the
Markdown engine's text link regex so code spans, fences and authored links
stay plain without a second Markdown parse while streaming. The reference
alternative sits before path recognition so `group/project#12` is not read
as a file path.
* fix(app): keep http:// for self-hosted forge web links
A self-hosted forge cloned over http:// serves its web UI over http on
the same origin. Forcing https made reference, blob and tree links fail
against an HTTP-only port. Cloud hosts and SSH remotes stay on https.
