fix(rules): a grazed caster cell no longer shortens a line spell - SRD Aiming a Spell: a line 'starts from any corner of your square and extends to the limit of its range' (Lightning Bolt: 'The bolt begins at your fingertips'), so the caster's own squares are origin space the line starts PAST and must not consume one of the length_cells squares; line_cells took a fixed ray[1:length_cells+1] window and dropped caster cells inside it, so a 2x2 caster's line came out one square short per grazed footprint cell (the old code documented this as a simplification); the ray is now extended (reach = length_cells + 1 + len(caster_cells)) and caster cells are skipped WITHOUT spending a length slot, so a multi-cell line runs its full length starting just past the footprint; 1x1 casters are bit-identical (the only skipped cell is the origin at ray[0], already outside the counted window); the barrier/LoE stop and out-of-bounds semantics are unchanged (a straight ray never re-enters a convex map); golden untouched (no line spell in it); +3 tests (grazed-cell full-length template, 1x1 bit-identical regression, engine-level reach of a foe the short line missed)
