- test_update_stash_recovery: add merge-base handler for the force-update
rewind guard probe (origin/master is a descendant of HEAD -> not a rewind)
- test_security_review_fixes: fake_check accepts channel kwarg
- i18n.js: native translations of the 4 update-channel keys for all 14
non-English locales (locale-coverage tests enforce key presence)
On Windows a reserved-device-name file (nul/con/prn/aux/com1-9/lpt1-9) can land
in the working tree (e.g. a shell command redirecting to `> nul` under Git Bash,
which treats it as a literal filename). git can't delete it via the normal Win32
path, so `git clean -fd` exits non-zero — and force_apply_update treated that as
fatal, aborting the whole force update with 'Failed to remove untracked files
before force reset' and leaving the user stuck.
The clean is now best-effort: a failure is logged (stderr captured for
diagnostics) but non-fatal, because the subsequent `git reset --hard` overwrites
any tracked-file collisions regardless, and residual untracked files git can't
delete are harmless. Updates the prior test that asserted the (buggy) fatal
behavior to the corrected non-fatal contract, plus a new regression test.
