giles 9b060ef8c5 Bytecode compiler: desugar let-match, fix SPA navigation ...

The bytecode compiler now handles let-match (both variants):
- Variant 1: (let-match name expr {:k v} body...) — named binding + destructure
- Variant 2: (let-match {:k v} expr body...) — pattern-only destructure

Desugars to sequential let + get calls — no new opcodes needed.

This was the last blocker for SPA navigation. The bytecoded orchestration
and router modules used let-match which compiled to CALL_PRIM "let-match"
(undefined at runtime). Now desugared at compile time.

Also synced dist/sx/ sources with web/ and recompiled all 26 .sxbc modules.

2650/2650 tests pass.
