HS runtime: empty/swap/compound events, host-set! fix — 403→423 (51%)

Browse Source 
- Fix host-set → host-set! in emit-inc/emit-dec (increment/decrement properties)
- Implement empty/clear command: parser dispatch, compiler, polymorphic runtime
- Implement swap command: parser dispatch, compiler (let+do temp swap pattern)
- Add parse-compound-event-name: joins dot/colon tokens (example.event, htmx:load)
- Add hs-compile to source parser (was only in WASM deploy copy)
- Add clear/swap to tokenizer keywords and cmd-kw? list
- Generator: fix run() with extra args, String.raw support
