The dynamic Config array conversion (Todo 2.1 in the plan) was accidentally
omitted during Wave 2 — only the DwindleNode and dual client arrays were done.
This commit implements the missing work:
- Convert Config keybinds/buttons/scrolls from fixed-size arrays
(keybinds[128]) to pointer+count+cap (keybinds, nkeybinds, keybinds_cap)
- config_load allocates with ecalloc(16) for each array, doubles on overflow
- on_config_reload and do_reload use deep-copy protocol:
free old arrays → *newcfg → zero source pointers
- sizeof(Config): ~250 KB → ~28 KB (latest measurement)
- Zero-warning build
