env.vim sets g:loaded_X for twelve built-in plugins to short-circuit
them. A prior fix corrected the casing on g:loaded_logiPat, but four
of those plugins actually check the unscoped loaded_X form, not
g:loaded_X — so those four guards have been doing nothing.
Affected (all old runtime plugins predating the g:loaded_ convention):
- gzip.vim checks `loaded_gzip`
- logiPat.vim checks `loaded_logiPat`
- rrhelper.vim checks `loaded_rrhelper`
- spellfile.vim checks `loaded_spellfile_plugin`
Set both forms (g: and unscoped) for those four — belt and
suspenders. Empirically saves ~270μs at startup, mostly from gzip
which was loading its full autocmd group on every launch.
Add a regression assertion: source .vimrc, verify the four unscoped
guards exist.
Closes#81
Replace the monolithic 1268-line .vimrc with a thin loader that sources
12 modules under modules/ (env, plugins, core, ui, editing, navigation,
lsp, lint, git, writing, languages, tools). Each module is independently
readable and can be toggled by commenting one line.
Add interactive tutorial (tutor/chopsticks.tutor) with 10 lessons covering
all features. Users can run :ChopsticksLearn to start.
