By default, the agent now enables all available data plane protocols
starting with `tcp-tls,wg-quic`, removing the need to manually pass `--protocol`
to enable HTTPS-camouflage transport. The `--protocol` option remains available
to explicitly restrict or select specific protocols (or reorder their priority).
Furthermore, in `crates/tsunagi-tcp-tls`, if default port 443 is unavailable
(e.g., due to permission constraints or address in use), the transport now
attempts fallback port 8443, and if 8443 is also unavailable, gracefully falls
back to an ephemeral port rather than failing agent startup.
Key changes:
- In `crates/tsunagi-cli/src/main.rs`, update `UpArgs::protocols` default_value
to `"tcp-tls,wg-quic"`.
- In `crates/tsunagi-cli/src/main.rs`, reorder `PROTOCOLS` registry with `tcp-tls`
first, followed by `wg-quic`.
- In `crates/tsunagi-tcp-tls/src/transport.rs`, add multi-tier fallback
(443 -> 8443 -> ephemeral) for unconstrained port bindings.
Validation on Linux:
- cargo fmt --all -- --check passed.
- cargo clippy --locked --workspace --all-targets -- -D warnings passed.
- cargo test --locked --workspace --all-targets passed (349 tests passed).
- cargo build --release passed.
