PKG-13: the no-op half of the pre-deploy check has never run as documented

⚠️ THE INVOCATION ON PKG-09's CARD AND IN THE TOOL'S OWN DOCSTRING RUNS ONLY HALF THE CHECK. The container runs as uid 0 against a checkout owned by the operator, and git refuses that: fatal: detected dubious ownership in repository at '/w/goodwe-addon' `_git` returned non-zero, `last_version_change()` returned None, and the silent-no-op check - THE REASON PKG-09 EXISTS - reported SKIPPED. Measured, on the documented command against release/1.0: ⚠️ SKIPPED: could not ask git what changed since the last bump; the no-op check is INCONCLUSIVE, not clean NOT CLEARED and with `--user $(id -u):$(id -g)`, unchanged otherwise: no runtime change since the last bump - nothing to deploy CLEARED for deploy. ⚠️ THE TWO HALVES WERE MUTUALLY EXCLUSIVE ACROSS THE TWO DOCUMENTED ENVIRONMENTS. In the container the validator ran and git skipped; on a bare host git ran and the validator skipped on aiohttp. NEITHER DOCUMENTED COMMAND RAN BOTH. The pre-0.9.0 clearance was sound only because it happened to be driven as two separate invocations. ⚠️ AND IT WAS INVISIBLE IN THE ONLY CASE ANYONE HAD RUN. `main()` consults the git result only when `shipped == deployed`; every real run so far compared 0.7.0 against 0.9.0 and printed its verdict without ever needing git. FIXED IN `_git()` WITH `safe.directory`, NOT BY DOCUMENTING `--user`. The tool should be correct however it is invoked rather than requiring every future caller to remember a flag; the read is read-only, on a repository the operator is about to deploy from. ⚠️ WHY THE TESTS COULD NOT SEE IT, WHICH IS THE FINDING BEHIND THE FINDING. `test_version_gate.py` invokes the gate with `sys.executable` against fixtures it creates as its own uid, so no fixture could ever meet an ownership mismatch. MUTATION.md habit 4 in a fourth shape, inside the file written to prevent it - after the pickaxe bug, after the one-bump history, after the filter-only survivor. Two fixtures added: - a directory that is NOT a git repository, so the lookup genuinely fails: the gate must exit 2 saying INCONCLUSIVE and must NOT say CLEARED. - ⚠️ THE EXIT CODES PINNED BY VALUE, NOT BY TRUTHINESS. `returncode != 0` is satisfied by collapsing NOT-CLEARED into REFUSED, which review found the earlier draft could not tell apart. 1 says "this deploy is wrong"; 2 says "nobody checked". Driven: collapsing 2 into 1 now goes red on exactly that check. Suite: 26 files, all pass.

+    ⚠️ WITHOUT `safe.directory` THIS TOOL SILENTLY DID HALF ITS JOB. The
+    invocation this file's own docstring documents runs the container as uid 0
+    against a checkout owned by the operator, and git refuses that:
+
+        fatal: detected dubious ownership in repository at '/w/goodwe-addon'
+
+    `_git` then returned non-zero, `last_version_change()` returned None, and
+    the no-op check reported SKIPPED - so **the silent-no-op half, which is the
+    reason this file exists, had never once run in its documented form.**
+
+    It degraded honestly: exit 2, INCONCLUSIVE, never a false clearance. But a
+    check that cannot fire is not a check, and the two documented environments
+    were mutually exclusive - in the container the validator ran and git
+    skipped; on a bare host git ran and the validator skipped on aiohttp.
+    Neither documented command ran both halves.

+    `safe.directory` is the right fix rather than `--user`: it makes the tool
