Match upstream vimwiki's insert-mode list editing:
<C-D> list_change_level(-1) dedent current item
<C-T> list_change_level(+1) indent current item
<C-L><C-J> list_cycle_symbol(+1) cycle marker forward
<C-L><C-K> list_cycle_symbol(-1) cycle marker backward
<C-L><C-M> list_toggle_or_add_chk toggle if has checkbox, else add `[ ]`
Cycle order matches vimwiki's canonical run:
- → * → # → 1. → 1) → a) → A) → i) → I) → (wrap)
Both Lua and VimL paths wired. Lua callbacks fire directly (no `<C-o>`
dance) since list_change_level / changeSymbol mutate the buffer via
the LSP applyEdit pipeline, which works cleanly in insert mode. VimL
keeps the `<C-o>:call …<CR>` idiom since that's the standard there.
Harness adds 5 cases covering the new insert-mode bindings plus one
direct LSP roundtrip for changeSymbol — surfaced a long-standing
stale-binary footgun in test-keymaps.sh (rebuilt only when bin was
missing; now rebuilds every run since incremental cargo is fast).
Harness also captures server log_messages and dumps them on failure
so future swallowed-error bugs (Err → log + Ok(None)) are visible.
Gates: 421 Rust / 25 Neovim / 12 Vim.
