Krzysztof kuhy Rudnicki 4cfc3fdde1 Test bt_report.sh to 100%: allowlist 98 -> 97
First of the 16 untested fixes/lib libs. Measured 37/37 = 100.00% through
lib/tests/run_all.sh, twice, the second run at --min 100 (exit 0), then
removed from the allowlist and confirmed with the real gate and no
exemption.

Adds two reusable pieces rather than a per-family harness clone:

- lib_test_core.sh -- PASS/FAIL tally, _t_eq/_t_contains/_t_lacks, a
  mktemp -d sandbox wiped on EXIT, a FAKE_BIN stub dir on PATH, and
  _t_stub/_t_unstub. _t_unstub runs `hash -r`: deleting a stub file alone
  does not drop bash's cached executable path, so the real binary would
  never be reached again.
- bt_harness.sh -- sources the core, sources the real scripts/lib/common.sh
  for the production log_*/has_cmd helpers (verified inert at source time),
  and redefines _btctl and apply_fix verbatim from fix_bluetooth.sh, since
  those live in the entry script rather than in any lib. Same trade-off
  pacman_hook_stall_harness.sh already makes with log_size.

pacman_hook_stall_harness.sh is deliberately left alone: its six libs are
already off the allowlist, i.e. gated at 100% with no exemption, so
refactoring it onto the new core would risk banked work for no gain. jscpd
reads 1.6% against the hook's own flags, and **/lib/tests/** is excluded
from that scan anyway, so the duplication budget is not at stake.

_t_only_path exists because every tool these libs call (usbreset, pactl,
lsusb, ...) genuinely exists on an Arch desktop: a prepended stub dir
cannot exercise a "not installed" branch, so those cases drop PATH to
FAKE_BIN alone.

The three coverage runs were made in a detached worktree: a second session
was writing to this repo concurrently, and the jail aborts on any
working-tree delta during a run.
