fanyang 9e9916efa5 fix(connector): skip self-connection when peer shares local interface IPs (#1941 )

When two EasyTier instances run on the same machine and share the same
network, the direct connector would expand a remote peer's 0.0.0.0
listener into local interface IPs and then attempt to connect to
itself, causing an infinite loop of failed connection attempts.

The existing `peer_id != my_peer_id` guard does not cover this case
because the two instances have different peer IDs despite sharing the
same physical network interfaces.

Fix by adding a self-connection check in `spawn_direct_connect_task`:
before spawning a connect task, compare the candidate (scheme, IP,
port) against the local running listeners. If a local listener matches
on all three dimensions — accounting for 0.0.0.0/:: wildcards by
checking membership in the local interface IP sets — the candidate is
silently dropped with a DEBUG log message.

The fix covers all four code paths:
- IPv4 unspecified (0.0.0.0) expansion loop
- IPv4 specific-address branch
- IPv6 unspecified (::) expansion loop
- IPv6 specific-address branch

The TESTING flag logic is untouched so existing unit tests are
unaffected.

* refactor(connector): replace is_self_connect closure with GlobalCtx::should_deny_proxy (#1954)
