fix(config): cleanup bugs, redundancy, and add agent-friendly auto-reload

- remove broken mini.files mappings (plugin disabled; yazi is used now)
- dedupe tint.nvim spec (drop plugins/theme.lua, keep ui.lua)
- drop dead copilot cmp source + moot Supermaven symbol (Supermaven stays inline)
- remove yaml from biome formatters (biome has no yaml support)
- collapse 3x biome chain to a single biome-check pass
- remove duplicate insert-mode jk mapping
- lazy-load tailwind-tools by filetype
- diagnostics: update_in_insert = false
- untrack .nvimlog, add .gitignore
- auto-reload files changed on disk (autoread + checktime autocmds)
