Merge remote-tracking branch 'origin/main' into split/permission-mode-and-classifier

* test(tui): pin the cwd in tests that assert text is absent from the view

Nine tests built their model with an empty Options.Cwd, so newModel took
the package directory and the title bar showed the developer's real
branch and checkout path. Each then asserted that some text was absent
from the whole view, and failed wherever that branch or path happened to
contain it: TestSuggestionOverlayRenders on a branch with /model in its
name, TestSuggestionOverlayCapsRowsWithoutMoreText on a branch or path
containing "more" or "compact", the provider wizard tests on "offline",
"chatgpt" or "gpt-4.1", and so on.

They now pin Options.Cwd to isolatedCwd, a path that does not exist, so
no branch is read and the path is the same on every machine. A guard
test checks that isolatedCwd stays outside any git checkout.

* test(tui): make isolatedCwd fully qualified and absent by construction

The fixed /workspace/zero path could exist on some machine, a dev
container for one, and newModel would then read whatever is there. On
Windows it was also only drive-relative: \workspace\zero is not a fully
qualified path.

isolatedCwd is now a child of the home TestMain isolates that nothing
creates, so it is fully qualified, absent and outside any checkout on
every platform, and the title bar shows ~/not-a-checkout everywhere. A
t.TempDir path would have put the user name and the test name into the
view. The guard test checks all three properties.

* test(tui): clear the branch in view-test models instead of trusting the cwd

isolatedCwd is a child of the isolated home, which lives under the
temporary directory. With TMPDIR inside a checkout, gitBranch walks up
from that absent path to the checkout and puts its branch in the title
bar, so the guard failed on an ordinary branch and a colliding branch
broke the nine view tests again.

newViewTestModel now builds those models: it sets the isolated cwd and
clears the branch after construction, since no path can promise there
is no checkout above it. The guard keeps only what a path can promise
(fully qualified and absent), and a new test puts the home inside a
checkout on feat/model-picker and checks that neither that branch nor
the real checkout path reaches the view.

* test(tui): assert no checkout path reaches the view in the enclosing-checkout test

The test checked the branch strings and that the isolated cwd shows,
but a view could show both the isolated cwd and a real checkout path
without failing it. It now also asserts that neither the enclosing
checkout nor the directory the tests run from appears in the view.
