nvim: render markdown in the buffer

render-markdown.nvim draws headings, code blocks, tables and checkboxes in
place, in the one buffer, and leaves the cursor line raw so editing is
unaffected; <leader>mt toggles it. The markdown and markdown_inline parsers
join the install list, which also gives noice's LSP hover rendering the
parsers it was already set up to use.

None of the colourschemes here define the @markup.heading.N.markdown captures
the plugin colours headings from, so every level rendered alike. A ramp fills
them in, only where the theme left the group empty, and again on each theme
switch. Checked with the real config: 26 marks on a test file, conceallevel 3,
H1-H3 in distinct bold colours.

AGENTS.md also stops listing nvim as having no machine-local hook: lua/local.lua
is one, gitignored and loaded by cfg-watch after the plugins.
