hammerspoon: shared helpers move to dotlib.lua, which local.lua can require

A machine's local.lua is a separate chunk, so init.lua's locals were invisible
to it and anything it wanted -- hotkey(), the mod tables, type_text -- had to
be copied. They live in dotlib.lua now, linked beside init.lua, and both files
reach them the same way: require("dotlib").

init.lua keeps its own vocabulary by aliasing what it uses, so the 500 lines
below are untouched. It prepends its own directory to package.path first:
Hammerspoon already puts the config directory there (Contents/Resources/
setup.lua), but taking it from this file's path holds however the config was
found. A machine that pulls without re-linking has no dotlib.lua beside
init.lua, which would lose every hotkey silently -- that case notifies and
names the fix.

Checked with a stubbed hs: the module's hotkey, focus, execute, type_text and
type_current_date all behave, and local-example.lua binds its four keys
through it.
