v1.6.0

Completes coverage of the documented PixelLab v2 API — 72 → 84 tools. All 12 additions are retrieval or cleanup routes; every generation endpoint was already covered.

New tools

• Deletion: delete_tileset, delete_tileset_sidescroller, delete_isometric_tile, delete_tiles_pro
• Sidescroller tilesets: get_tileset_sidescroller, list_tilesets_sidescroller (previously create-only)
• list_tiles_pro, get_map_object
• delete_character_animations / delete_object_animations — all animations by default, or scoped via animation_type, animation_group_id, direction
• get_font_pro_job / get_portrait_character_pro_job — dedicated endpoints that get_job_status does not resolve

See CHANGELOG.md for details.
