CI log for the keymaps job showed Lua crashing with `attempt to call field 'get_clients' (a nil value)` plus a flood of `W18: Invalid character in group name` on the `@vimwiki*` highlight links. Both signal that apt's `neovim` package is too old (Ubuntu LTS ships 0.6/0.7) — `vim.lsp.get_clients` only landed in 0.10, and Tree-sitter-style `@group.modifier` highlight names only became valid sometime in the 0.8-ish era. Switched the installer to pull the official static tarball (`neovim/neovim/releases/v0.11.3/nvim-linux-x86_64.tar.gz`) and symlink it into `/usr/local/bin/nvim`. Vim from apt is kept — it only runs the pure-VimL harness so its age doesn't matter. Also added a defensive fallback in the harness: `get_lsp_clients = vim.lsp.get_clients or vim.lsp.get_active_clients`, plus a `server_capabilities` nil guard. Won't matter on the pinned 0.11 runner, but means a future regression that drops the deps will fail with a clear `lsp.attached` FAIL message instead of a Lua stack trace.
