wxjandClaude d57a0260e8 stable: revert multi-core, restore working single-core optimizations
Keep P0-P4 optimizations:
- Fragment mempool (frag_alloc/frag_free)
- WS frame alloca() dynamic stack
- Fragment read_offset (eliminate memmove)
- nclose busy-poll (replace cond_timedwait)
- Remove dead ng_tcp_out()

Revert experimental multi-core changes (moved to feature/multi-core):
- Worker arrays, TLS context switching
- RX hash distribution, TX multi-ring collection
