🧼 generate compact wcwidth tables

[natemoo-re]

Building on #35, reduces npm install size again:

• replaces the src/wcwidth.c implementation borrowed from termbox2 (~1,200 lines) with optimized tables generated by tasks/gen-wcwidth.ts
• tables are generated from official Unicode spec, only tracks the size of wide characters (width = 2) and zero-width characters (width = 0) instead of all ranges (width = 0 | 1 | 2)
• adds a gen-wcwidth task to regenerate tables when Unicode data updates
