Record the live box arrow grid so replay matches live paint

Browse Source 
Box analysis used the finger sample grid, so replay packed arrows into the contact zone. The pass now stores draw_arrows cells; stale box caches miss and re-run. Verified with shared and Studio tests, including a live-vs-replay canvas check.

**Force is stored too, and it is a recomputation, not a recording.** When the input is
not a recording — a bare video in a generated workspace — ``forces.csv`` does not exist,
so the only force there is the one the chain computes from the frames, read through the
same ``read_forces_from_sensor`` the live loop uses. It is stored *per frame*, behind
:data:`FRAME_FLAG_FORCE` and appended after the depth payload, so a build that does not
know the flag still reads every record correctly: a chunk's own offset table delimits a
record, and trailing bytes were always ignored. Six float32 values plus two flags cost
28 B/frame — 15 MB per ten minutes, against the 4,048 B the frame already costs — and
the format version is unchanged because nothing that could be read before reads
differently now. This is the one channel whose ``Provenance.sources`` entry is
``recomputed`` on the *synthetic* path and ``recorded`` beside a real ``forces.csv``:
the two must never be confused, which is what the field is for.
Sparse storage was measured and rejected: 4-byte indices per non-zero pixel cost
910 B for the worst non-empty frame against 486 B for the whole quantised map, because
a mostly-zero byte plane is nearly free for zlib while pixel indices are not. Island
