* build: replace luacheck with selene Problem: luacheck is unmaintained (last release 2018) and required suppressing four warning classes to avoid false positives. It also lacks first-class vim/neovim awareness. Solution: switch to selene with std='vim' for vim-aware linting. Replace the luacheck CI job with selene, update the Makefile lint target, and delete .luacheckrc. * build: add nix devshell and pre-commit hooks Problem: oil.nvim had no reproducible dev environment. The .envrc set up a Python venv for the now-removed docgen pipeline, and there were no pre-commit hooks for local formatting checks. Solution: add flake.nix with stylua, selene, and prettier in the devshell. Replace the stale Python .envrc with 'use flake'. Add .pre-commit-config.yaml with stylua and prettier hooks matching other plugins in the repo collection. * fix: format with stylua * build(selene): configure lints and add inline suppressions Problem: selene fails on 5 errors and 3 warnings from upstream code patterns that are intentional (mixed tables in config API, unused callback parameters, identical if branches for readability). Solution: globally allow mixed_table and unused_variable (high volume, inherent to the codebase design). Add inline selene:allow directives for the 8 remaining issues: if_same_then_else (4), mismatched_arg_count (1), empty_if (2), global_usage (1). Remove .envrc from tracking. * build: switch typecheck action to mrcjkb/lua-typecheck-action Problem: oil.nvim used stevearc/nvim-typecheck-action, which required cloning the action repo locally for the Makefile lint target. All other plugins in the collection use mrcjkb/lua-typecheck-action. Solution: swap to mrcjkb/lua-typecheck-action@v0 for consistency. Remove the nvim-typecheck-action git clone from the Makefile and .gitignore. Drop LuaLS from the local lint target since it requires a full language server install — CI handles it.
