feat: multi-listener with configurable proxy chaining

Each listener binds to its own port with an independent chain.
The "pool" keyword in a chain appends a random alive proxy from
the shared pool; multiple pool entries = multiple hops.

  :1080 -> Tor only (0 pool hops)
  :1081 -> Tor + 1 pool proxy
  :1082 -> Tor + 2 pool proxies

Shared resources (ProxyPool, Tor, metrics, semaphore, API) are
reused across listeners. FirstHopPool is shared per unique first
hop. Backward compatible: old listen/chain format still works.
