fix(shortcuts): keep shortcut contract in config/ (Rust include_str! path)

The shortcut contract (shortcutActions.ts + shortcutTypes.ts) is NOT a
pure-frontend file: src-tauri/src/cli/parse.rs include_str!s
'/../src/config/shortcutActions.ts' at compile time, so moving it to
lib/shortcuts/ (slice 7ad19671) broke the Rust build (couldn't read the file ->
dev build won't start). Revert the contract back to src/config/ — it has a
build-time backend path contract and belongs where Rust anchors it, not in lib/.
No Rust file touched (fix = restore the frontend path the backend expects).

cargo check green (13s), tsc 0, lint 0/0, frontend suite 319/2353 green.

Lesson: grep src-tauri for include_str!/include_bytes! '../src/...' before
moving ANY frontend file — Rust can pin a TS file by path.
