fleet(test): attribute FIRST-position to the fixture, not to the fix

Comment-only. The colon-padding note said the anchored regex 'rejects the
directory in FIRST position — which is exactly where the fix puts it'. True in
this fixture, which runs env -i with no MOSAIC_RUNTIME_BIN so the bootstrap
directory leads, but stated as a property of the fix. In general the directory
sits second, after MOSAIC_RUNTIME_BIN, and it reads as a contradiction of the
source comment corrected in c7ee3cb.

Found in review by rhodey, who also noted the same sentence is live in the PR
description. No executable line changed.

Resolving the acting identity and the read-back from the _same_ login that performs the write is essential: a write performed under an overridden login must be verified against that login's identity, not the host default's.

-### Identity-first principal resolution in the wrappers (#1280)
-
-`resolve_gitea_principal()` (detect-platform.sh) gives the write wrappers —
-`pr-create.sh`, `pr-merge.sh`, `pr-review.sh`, `issue-create.sh`, `issue-comment.sh` —
-ONE precedence for choosing the acting principal:
-
-1. an explicit `--login <name>` (now accepted by all five; operator intent beats
-   environment), then
-2. the per-agent identity above (`MOSAIC_GIT_IDENTITY` env / worktree
-   `mosaic.gitIdentity`) when a per-slot token exists — the wrapper then writes via the
-   REST API with that identity's token and never consults `tea`, so the tea login list
-   cannot shadow the requested principal, then
-3. the tea login list — the LAST resort, never the first, because it enumerates
-   whatever logins the host happens to hold and knows nothing about which seat is
-   calling.
-
-A requested identity whose per-slot token is absent, or a `--login` whose token cannot
-resolve host-bound, **fails loud** (nonzero, naming the identity/login and the expected
-slot) instead of silently writing under whatever account `tea` has configured — that
-silent fallthrough is defect #1280 (reviews, comments, merges, PRs and issues filed
-under the wrong account). `pr-merge.sh --dry-run` reports the principal the merge would
-act as, resolved exactly as the real merge resolves it. ⚠ A **workstation-global**
-`mosaic.gitIdentity` shadows every seat on that host (a fresh clone with no local value
-resolves the global one) — set it per-worktree, not with `--global`.
-
-The resolver is covered by `test-gitea-principal-resolution.sh`; the happy-path
-ordering (identity arm REACHED, not sitting behind a tea failure) by
-`test-pr-create-identity-first.sh`; merge credential binding by
-`test-pr-merge-principal-resolution.sh`.

-#   4. identity unset + no --login -> default mode: the tea login list

-# Load-bearing regression harness for pr-create.sh identity-first principal
-# resolution (mosaicstack/stack #1280).
-#
-# The failure this harness is written down to catch: `MOSAIC_GIT_IDENTITY=fargo
-# pr-create.sh …` produces a PR attributed to `mos-dt-0` (whichever account the
-# tea login list happens to hold). Before #1280 the identity-aware code existed
-# but sat on the API arm that only ran when the tea path FAILED — tea succeeded,
-# so the identity arm never executed, and every test that did not check ORDERING
-# passed. This harness checks ordering directly:
-#
-#   1. identity set + slot present -> the PR is created via the REST API with
-#      the identity's per-slot token (asserted by sentinel value AT the fake
-#      provider), and tea's `pr create` is NEVER invoked.
-#   2. identity set + slot ABSENT -> nonzero, stderr naming the identity and
-#      the expected slot path; neither tea `pr create` nor any API request
-#      fires. No silent fallback to the tea login list.
-#   3. identity set + --login -> --login wins: tea runs WITH the explicit
-#      --login, no API request.
-#   4. nothing set -> preserved behavior: tea path with the tea-list login.
-#
-# Uses a stubbed tea, a stubbed curl provider, stubbed credentials.json and
-# per-slot token under a fake HOME. NEVER reads real secrets or hits a live
-# forge — all assertions are against the stubs' logs.

-#      git config mosaic.gitIdentity > shared host credential. (The pre-#1280

-#      the login / the identity and its slot path).
-#   3. The real merge POST carries the resolved principal's credential and no
-#      other: --login merges with that login's tea-config token; an identity
-#      merges with the per-slot token; an unresolvable --login never reaches
-#      the provider.

-# Fixture pattern from test-pr-merge-head-pin.sh: the scripts under test are
