HOLD: measurement only, never merge. Its owner closes it after the run.

This adds only .measure/: the merge diffs of #28388 and #28015 into feat-cmux-next 27f2c06, and a script that measures the acpmux Rust panic ratchet on the tip, on tip+#28388 and on tip+#28015 (cmux-ci runs only at an open PR's head).

Summary by cubic

Measurement-only PR, never to merge; its owner closes it after the run. It measures the acpmux Rust panic ratchet on flat feat-cmux-next tip against base 976656f, since cmux-ci runs only at an open PR's head.

Adds .measure/measure.sh, which runs clippy with the ratchet flags on the tip and reports the four deny-ratcheted lint counts (indexing_slicing, string_slice, unwrap_used, expect_used) plus per-file hit lines for each configuration difference.

^{Written for commit 421e624. Summary will update on new commits.}
