Content-aware Remove: inpaint crate (PatchMatch completion) and a Fill spot mode

Browse Source 
New `inpaint` crate (L1): multi-scale patch-based completion with a PatchMatch
nearest-neighbour field, seeded by a membrane fill. Deterministic, no panics on
hostile sizes, cancellable. Ported from PhotoCraft (MIT OR Apache-2.0).

Remove tool: a fourth spot mode, `fill` ("Content-Aware"), rebuilds the spot
from patches of its surroundings instead of one source; coarse-to-fine, so the
structure is chosen at a scale set by the spot size and preview and export agree
(tested). spot.add leaves its source unset.

M. Irani, Space-Time Completion of Video (TPAMI 2007); P. Perez et al., Poisson
Image Editing (SIGGRAPH 2003) for the membrane fill; code ported from PhotoCraft
crates/algo/src/inpaint.rs + poisson.rs (a680ed22).
