config.zig: every binding and every piece of Look syntax in one file

Retargeting a key, a mouse chord or a spelling is now an edit to src/config.zig
and nothing else. Three parts in reading order: pardes's own bindings (where a
reader lands), the Look/Exec syntax, then the helix keymap under a banner
saying hxdiff/hxparity are differential suites against real helix, so a key
moved there is a divergence and not a tweak.

The bindings are data a comptime loop can walk, because the builtin index is
going to walk them.

Duplication this cut: is/isC/isA became one hit(key, chords) over ~132 call
sites, and a binding being a LIST collapses the letter-or-arrow chains;
swap_enter_tab is gone, replaced by look_key/exec_key that can point anywhere;
the four focus builtins' h/j/k/l lived hardcoded in two places and is now one
table.

No golden moved.
