Vendored from upstream, pinned by commit:

- lite-xl-plugins   https://github.com/lite-xl/lite-xl-plugins   @ 31eef29 (master, 2026-09)
    plugins/: gitstatus, gitopen, fontconfig, open_ext, select_colorscheme,
    smoothcaret, nerdicons, language_* (all 104; none overlap the ones bundled
    in the core data/ directory)
- lite-xl-gitpanel  (own plugin, source tree lite-xl-gitpanel)  @ 0731a63 (main, 2026-09)
    plugins/: gitpanel -- git panel integrated into the treeview pane
    (changes, staging, commits, history) with a toolbar toggle button;
    uses the bundled language_diff for commit diff highlighting

- lite-xl-lsp       https://github.com/lite-xl/lite-xl-lsp       @ d1432ae (master, 2026-09)
    vendored whole as plugins/lsp/ (screenshots removed)
- lite-xl-widgets   https://github.com/lite-xl/lite-xl-widgets   @ dcf1c8c
    NOT vendored: only the settings plugin needs it, and settings@master
    requires libraries.widget.fonts which does not exist in the widgets
    repository at any revision, so settings cannot load. Revisit when
    upstream publishes the missing widget.
- nerdicons font mapping: plugins/font_symbols_nerdfont_mono_regular.lua
    shipped as usr/share/lite-xl/libraries/font_symbols_nerdfont_mono_regular.lua
    with the font path patched from USERDIR to DATADIR, plus the
    Symbols Nerd Font Mono TTF (SIL OFL 1.1) next to it.

Refresh by re-cloning the sources at a new commit and re-applying the single
sed patch to the font mapping path.
