FN-7575 (issue #1916) added "Current version:" / "Target release:" lines to
GitHubIssueCommentService, but that service is gated on `githubCommentOnDone`
— default false, with no Settings UI — so it effectively never fires. The
"✅ Done —" comments on linked issues are posted by GitHubTrackingCommentService,
which had no version logic. The lines were invisible in production for ~10 days;
issue #1916's own close comment is the proof.
Extract the self-repo check and next-minor computation into a shared
fusion-release-version.ts and apply it across all four done-comment surfaces
(GitHub/GitLab x tracking/issue) so they cannot drift again.
- Release lines join `optionalLines` rather than being appended to the finished
string, so they count against DONE_COMMENT_MAX_LENGTH and shrink the title
budget; appending would silently blow the cap on long titles.
- Version resolution is a lazy resolver, so getCliPackageVersion()'s filesystem
walk only runs for self-repo comments.
- GitLab self-repo matching uses item.projectPath: resolveGitLabTargetFromItem()
prefers the numeric projectId, which never matches the slug.
- Non-self repos stay byte-for-byte unchanged (asserted).
Per the Surface Enumeration rule, regression tests assert the invariant across
every done-comment surface — both the pure formatters and the services that
post — plus case-insensitive slug matching (issue #1916 is "Runfusion/Fusion"),
in-progress transitions, the 0.0.0 sentinel, unparseable versions, the
lazy-resolution guarantee, and the truncation ladder under the length cap.
Verified non-vacuous: 10 of the new tests fail against the pre-fix source.
