Add optional 'bandwidth' field to proxy groups for shared bidirectional
rate limiting. Traffic routed through a bandwidth-limited group is
throttled using a token-bucket limiter (bits/sec) shared across all
connections in the group.
Config syntax:
proxy-groups:
- name: SPEED-LIMITED
type: select
bandwidth: 500k # 500 Kbps (accepts: k/m/g/bps)
proxies:
- DIRECT
Implementation:
- New component/ratelimit package with Limiter, RateLimitedConn (net.Conn),
limitedCConn (C.Conn with ReadBuffer/WriteBuffer overrides to prevent
bufio.Copy/Relay bypass via sing ExtendedConn promotion), and
limitedPacketConn (UDP with WaitReadFrom zero-copy path coverage)
- GroupBase stores shared *Limiter; GroupBase.LimitConn/LimitPacketConn
wrap connections after dial in all group DialContext/ListenPacketContext
- ParseBandwidth() handles '500k', '1m', '1Mbps', bare integers (Mbps)
- Default bandwidth: 0 = unlimited (backward compatible)
- transport/jls/jls.go refactored to use shared ratelimit package,
removing duplicate rate limiter code
