Owner

Stacks on #61. Closes charles/loom#23.

Reusable Mask struct that drives the inpaint canvas overlay. Pixel-addressed grayscale buffer with cursor + brush state, paint(value) circle fill, move_cursor with edge clamping, adjust_brush clamped [1, 128], and to_png_bytes() returning an 8-bit PNG.

Tests (4 new, 74 total)

Circle paint produces the expected (~π·r²) pixel count
Cursor clamps at edges
PNG round-trip preserves the filled pixel count
Brush radius clamps at both ends

Out of scope

Full-screen overlay integration with image rendering happens in the glue PR that threads Box<dyn ImageRenderer> through AppCtx. Today the Mask struct is the part the overlay composes on top of.

feat(tui): inpainting canvas — Mask state and PNG export e8a784293d

First half of the inpaint canvas overlay: a reusable Mask struct that
holds a pixel-addressed grayscale buffer, tracks cursor + brush radius,
and supports move_cursor, paint(value), clear, adjust_brush, and
to_png_bytes() export. Circle fill matches the expected ~π·r² pixel
count for a radius-8 stamp and survives a PNG round-trip.

The full-screen overlay that hooks this into AppCtx and exports the
mask path back into GenerateScreen.params.mask_image_path lands with
the image-renderer wiring in a later PR — the unit here is the mask
state machine that the overlay composes on top of.

Closes charles/loom#23
