feat: Phase 8.3 true non-blocking async/await with stackful coroutines
- C runtime: ucontext-based coroutines (bux_async_spawn/yield/await/run)
- Round-robin scheduler in bux_async_run() manages ready queue
- spawn Func() without args → bux_async_spawn() creates coroutine
- await → blocks/yields until coroutine completes
- async func → emitted as regular C function, runs on dedicated stack
- Interleaved execution: multiple coroutines yield cooperatively
- Example: examples/async.bux demonstrates WorkA/WorkB interleaving
- All 20 examples pass, selfhost build works

feat: Phase 8.3 async/await syntax + runtime
- AST: declFuncIsAsync flag, ekAwait expression kind
- Parser: async func declarations, expr.await postfix operator
- Sema: allow await anywhere (blocks current thread until task completes)
- HIR: ekAwait lowered to bux_task_join(handle) call
- C backend: async func emitted as regular function
- Example: examples/async.bux + examples_pkg/async project
- All 20 existing examples pass, selfhost build works
