chore(ipc): bootstrap tauri-specta generator (1 command, no cutover)

Stand up the FE<->BE contract pipeline end to end with near-zero surface: a
tauri_specta::Builder collects one proven command (greet) and exports typed TS
bindings to src/generated/bindings.ts. The existing generate_handler! stays the
live invoke handler — no FE change yet.

Safety: the export runs only under #[cfg(debug_assertions)] (debug launch) and a
headless test, never in a release build, so a specta RC break can never block a
release cargo build; the committed bindings.ts is plain TypeScript for tsc. The
snapshot is committed (gitignore exception) so CI diffs catch contract drift.

Pinned deps: specta / tauri-specta =2.0.0-rc.25, specta-typescript =0.0.12 (the
latest mutually-consistent set; rc.21 + specta-typescript 0.0.9 no longer resolve).
Grow collect_commands! crate-by-crate next, starting with psysonic-library.
