feat: add socket activation and bridge support for AsyncConnection (#143)

## Summary

- Add `AsyncConnection::with_activate()` for systemd-style socket
activation - spawns a server subprocess with `LISTEN_FDS`, `LISTEN_PID`,
and `LISTEN_FDNAMES` environment variables
- Add `AsyncConnection::with_bridge()` for connecting through
stdin/stdout bridge commands (e.g., `ssh host varlink bridge`)
- Add socket activation support to async server (`listen_async`) -
detects activation via environment variables and uses the passed fd
instead of binding
- Fix fd duplication bug in sync client's `with_activate`
- Fix `varlink bridge --connect` mode where no child process exists
- Properly kill spawned child processes when `AsyncConnection` is
dropped

## Test plan

- [x] `cargo test` - all existing tests pass
- [x] New integration tests in `async_more` example:
  - `test_with_activate` - verifies socket activation flow
- `test_with_bridge` - verifies bridge through `varlink bridge
--connect`
- [x] Verified no orphan processes after test completion
