fix(git-tools): issue-view shows comment bodies and names the real tea failure (#1357)

Four defects in issue-view.sh, each pinned by the new hermetic suite
test-issue-view-comments.sh (mock tea + curl, sandboxed repo):

F1  tea exits 1 in any repo with extensions.worktreeconfig=true. The wrapper
    now names that as a git-config condition and falls back to the API.
F2  The API fallback dumped raw issue JSON, which carries only a comment
    COUNT. It now fetches /comments and renders issue + comment bodies.
F3  The tea path never passed --comments, so comment bodies were never shown
    non-interactively. It now does.
F4  Every tea failure printed the REVOKED OR STALE TOKEN note. The wrapper now
    relays tea's own error line and only hints at credentials when tea did.

The suite joins ci.yml and the verify-release canonical list (mirror test).

Closes #1357
