#### Brief overview of PR changes/additions
- `ProfileLifecycleTest` (merged this morning in #9776) seeds
`$XDG_CONFIG_HOME/mudlet` without the `profiles/` subdirectory that
#9712 made the opt-in, so on any machine whose `~/.config/mudlet` holds
profiles it resolves to that instead and fails its own line 331
assertion. Reproduced here before the one-line fix. Its build legs all
finished on 10 Aug 13:52-14:55 UTC and #9712 merged at 22:17 that
evening, so it was merged 16 hours later on green CI that predates the
rule it breaks.
- `XdgRecipeConsistencyTest` stops the next one. It scans `test/*.cpp`
and `test/functional_tests/*.cpp` the way `CMakeListsConsistencyTest`
scans `src/`, and fails on a `mkpath()`/`mkdir()` whose argument spells
a path ending in `/mudlet` unless the file also creates the `profiles/`
opt-in. A test that means it says so with an `xdg-recipe-guard: allow`
comment.
- Comments, strings and raw strings are parsed out first, so a recipe in
prose is not code and an assertion against a `"%1/mudlet"` literal is
not a creation. The sweep reads this file too: its own fixtures spell
the stale recipe out inside string literals.
Test case: the sweep names `ProfileLifecycleTest.cpp:317` before the
fix, and both pre-#9810 files at lines 154 and 173 when those are
checked out of `8901b59d8`; the other 99 test sources are clean, and the
suite is 98/98 locally.
