refactor: split th_2_core.js into 12 modules, rename all files to 2-digit numbering
- Split th_2_core.js (4715 lines, 177KB) into: th_02_core.js, th_03_icon.js, th_04_theme.js, th_05_persistence.js, th_06_icon_parser.js, th_07_shortcut.js, th_08_content.js, th_09_animation.js, th_10_shell.js, th_11_action.js, th_12_rebuild.js, th_13_panel_ui.js - Rename existing: th_1_base→th_01_base, th_3_panels→th_14_panels, th_4_extra→th_15_extra, th_5_entry→th_16_entry - Update ToolHub.js MODULE_MANIFEST, modules array, and critical module check
