README previously punted on the config schema with a "full key list in
internal/config/config.go" pointer. New docs/config.md walks every
TOML key the daemon reads — top-level, [vm_defaults], [[file_sync]] —
with type, default, and a one-sentence description per row, plus a
copy-pasteable example at the bottom.
Sourced 1:1 from internal/config/config.go's fileConfig (and the
defaults in load() + internal/model/types.go), so it stays accurate
as long as those structs are the schema source of truth.
README's existing config section now points at docs/config.md, and
the "Further reading" list gets it as the first bullet.
