Point docs and comments at the files code moved to

Documentation only, no code change: README's reading order and layout,
docs/design.typ's paragraph on where pane kinds and editor parts live,
docs/helix-keys.md's code map (normalInput and the executors now in
normal.zig and edit.zig, insertTab in edit.zig), docs/open-questions.md
(execute and ttyForDir in exec.zig), and the comments that named pardes.zig
for fold, Cell, takesCommandLine and runBuiltin (tools/gen_themes.zig,
themes/helix.zig, detached/wire.zig, host_io.zig, lsp_zls.zig).
docs/design.pdf is a retained fixture and is not regenerated.
