refactor(agent/runtime): pet — shared flood/placement helpers in atlas, provider resolution loop, dead helpers removed
- atlas: _border_flood/_unvisited_components/_place/_clear_region/_remove_masked
replace 6 hand-rolled flood + canvas-composite loops; _sever_expected_gutters
uses channel ops instead of per-pixel writes; dead _color_distance,
_has_slot_padding, _slot_bounds, atlas_to_webp_bytes, FRAME_COUNTS (0 refs).
- render/store: dead _open_sheet/_png_bytes/_union_alpha_bbox/_thumbs_dir removed.
- imagegen: _available() unifies 3 provider-availability checks; forced/preferred
provider resolution collapsed into one ordered loop (same precedence).
- state: derive_pet_state as a ranked table (same priority order).
- Comment/docstring compaction keeping the pipeline invariants.
