chore: remove 15 unused config directories and stale references

Drop config folders (aerospace, aqua, asdf, direnv, flipperdevices,
ghostty, htop, misc, nano, task, tealdeer, tms, wtf, yamlfmt,
yamllint) along with starship.toml, nbrc, and aerospace scripts/docs.

Clean up references in dfm, _dfm completions, bashrc, exports, and
exports-lakka to match.
