rootandClaude Opus 5 e147dd6d21 Add a four-direction walk demo that seeds its own sprite sheet ...

tools/seed-actor.mjs builds the project Actor demo: it uploads
tools/assets/Actor1.png, slices the 576x384 sheet into the 96 cells of a
12x8 grid (48x48 each, no remainder) and wears the character in the top
left corner. Walking is four ping-pong animations of three frames, which
is the original RPG-Maker walk cycle; standing is the middle frame of the
row, not an animation.

The graph pastes walk- or idle- in front of the direction faced and wears
the result, so eight cases need no branch tree - the List node only holds
numbers. Which way it looks is the key pressed last, corrected whenever
only one axis is still held, or letting go of one key of a diagonal would
walk backwards. Axis input already normalizes its vector.

tools/lib/projects.mjs gains uploadTexture, since data/textures/ is
git-ignored and a seed that ships its picture has to send it. The harness
gains w/a/s/d and keyDown/keyUp halves, because holdKey cannot express two
presses that overlap - which is what a diagonal is.

tools/smoke-actor.mjs plays it in 19 checks and reads the drawn pixels at
the camera edge, where the bounds hold him walking on the spot: three
distinct frames walking, one standing.
