Review remediation for two correctness holes in the #865 fix:
BLOCKER 1 — issue-comment.sh read-back was body-only across all history:
if `tea comment` silently no-opped (the #865 bug) while an identically
bodied comment already existed from a prior run, the read-back matched the
OLD comment and falsely reported success. Now record the pre-write maximum
comment id as a boundary and require a comment with id > boundary AND exact
body match; monotonic Gitea ids make id > boundary mean "created by this
write". Fails closed otherwise.
BLOCKER 2 — pr-review.sh approve/reject trusted tea's exit code for the
review STATE (same never-trust-exit-zero defect class as #865). Removed the
TODO deferral and added a real bounded read-back: record the max review id
before `tea pr approve`/`reject`, then require a review with id > boundary,
the expected state (APPROVED / REQUEST_CHANGES), and commit_id equal to the
PR's current head. Fails closed if absent.
Tests: extended test-pr-review-gitea-comment.sh to model and assert the new
review-state read-back (guardrails preserved, assertions added). Added
test-issue-comment-readback.sh proving the pre-existing-identical-body
false positive now fails closed and a genuinely new comment verifies.

issue-comment.sh called the non-existent `tea issue comment` subcommand
form; tea 0.11.1 silently no-ops and exits 0 instead of erroring, producing
a false-success write. Switch to the top-level `tea comment <index> <body>`
form and add fail-closed REST read-back verification so the wrapper no
longer trusts tea's exit code alone.
pr-review.sh's comment path was already fixed for this bug by #812/#835
(routes through a read-back-verified REST comment API instead of any
tea comment subcommand); this change formalizes an explicit --login
override flag there too and documents the after-detection last-wins
--login ordering, consistent with issue-comment.sh.
