Replace the deprecated config.toml with an explicit, self-documenting
owlry.lua. Drop config.toml (ignored once owlry.lua exists; removed in
owlry 3.0). Disable the ssh provider (SSH is done from a terminal) and
keep filesearch out of the global set, enabling it only in a new dev
profile scoped to ~/Dev. Bump frecency_weight to 0.5, set tabs to
app/clipboard/emoji. Modernize the dmenu scripts to 'owlry dmenu'.
