test(phys): A6.P5 fixture — 3 ticks from live door-stuck capture

over-penetration-capture.jsonl is 3 records extracted from
door-stuck-capture.jsonl: the cell-crossing over-penetration tick
(0xA9B4013F -> 0xA9B40150, sphere committed 0.27m INTO slab), a
stuck-position hit=yes tick, and a stuck-position hit=no tick. Drives
the A6.P5 replay tests that prove the cellSet gate removal closes both
the over-penetration and the intermittent-visibility bugs.

extract-records.ps1 is a one-shot extractor; reusable if we capture more.
Source captures (door-stuck-*.jsonl, door-stuck-*.launch.log) gitignored.
