Subject: Split crates/config/src/lib.rs (1441 lines) into engine/

Pure reorganization, no behavior change - verified by diffing the
function-name and struct/enum-name sets before/after (both identical)
plus a full cargo test pass. lib.rs is now a thin shim (mod
declarations + pub use) since a crate root can't itself become a
directory; all the actual content moved into engine/, split along the
Lua API's own srd.*/srd.window.*/srd.layout.*/srd.workspace.*/
srd.theme.* namespace groupings the file's own section comments
already used:

- mod.rs: SharedState, Engine, ConfigError, and Engine's core methods
  (new/get/set/dispatch/reload/...).
- register.rs: register_srd_module, which wires every fn_* builder
  from every other file into the srd Lua table - the one place that
  genuinely needs to see all of them.
- general.rs/window.rs/layout.rs/workspace.rs/theme.rs: the fn_*
  builder methods themselves, one file per srd.* sub-namespace.
- support.rs: free functions shared across those (do_reload,
  parse_direction, flatten_table_into, validate, default_config) and
  the WindowAction enum.
- tests.rs: the ~300-line test module, left unsplit for the same
  shared-helper reason manager/tests.rs and udev's tests were.

~40 fn_* methods and the support.rs free functions/enum went from
private to pub(super): called across what are now sibling submodules,
which Rust's privacy model doesn't let see each other's private items.
