chore(plugins): purge typing-era tooling

Agent-driven work shifted nvim from writing code to reading and
reviewing it. Dropped:

- supermaven-nvim: inline AI completion duplicates the agent
- nvim-spectre: project-wide find/replace is now a prose request
- tailwind-tools: authoring aid for markup not hand-written
- editing.lua: hop.nvim plus ~85 lines of commented-out plugins
  (hardtime, ufo, local-highlight)
- telescope.nvim: second picker; gd/gv/gr now use fzf-lua, which
  was already bound to lsp_references
