Defame1297 c442f7eb85 fix(scripts): decide .vale.ini readability by reading it, not by access(2) ...

Issue #97 item 1 reports the unreadable-.vale.ini guard as untested. It
was worse: it was dead. `[[ -r ]]` is access(2), which asks whether the
permission bits would allow a read -- and for uid 0 that is yes even on
a mode-000 file. This hook runs at pre-push and the dev environment is
root, so the guard could never fire where it exists to fire. That is
why no uid-independent test for it existed; there was nothing to test.

Readability is now decided by actually reading (`cat`), which is
uid-independent and strictly stronger, catching EISDIR and EIO that
access(2) reports on neither. `cat`, not a `< "$ini"` redirect: opening
a directory for reading succeeds, only the read fails. The missing
branch moves to `-e`, so a directory sitting where the file belongs is
reported as unreadable rather than sending the reader hunting for a
deleted file.

The new case asserts the MESSAGE, not the exit code. With the guard
removed the script still exits 1 -- the greps hit the unreadable path
and blame a missing StylesPath on a file that has one. An exit-code-only
test would have been green with the guard deleted.

Also stops paying for vale in cases that only assert .vale.ini text:
21 of 28 script runs now mask it via the PATH_NO_VALE mechanism case 12
already builds, cutting the suite's bottleneck ~3.5x (issue #97 item 5).
The helper falls back to an unmasked run rather than skipping, so a
machine where masking is unavailable loses speed, never coverage.

That masking is a coverage gain, not only a speedup. With vale on PATH,
cases 8 and 9 could not detect deletion of the assertions they were
written to catch: a dropped StylesPath also breaks the glob probe, so
the script exited 1 for the wrong reason and both cases went green.
Verified against the pre-change files -- the same mutation was caught by
one incidental assertion before, and by three after.
