The wire changed after v0.3.3 (#1013), so this release bumps the number once and folds the note into the version 23 line (Principle 9). After merge, v0.3.4 is tagged on main and the release workflow publishes it. v0.3.4 replaces v0.3.3, whose downloads are then taken down, as v0.2.6 replaced v0.2.4 and v0.2.5.

Evidence

• cargo fmt --all --check passes.
• cargo nextest run -p tcode-protocol -p tcode-traverse -p tcode-client: 117 passed.
• No test or fixture hard-codes protocol version 22.

Merge Danger

Door: one-way once the tag is pushed and the release published. After that, v0.3.3 clients and hosts refuse to pair with v0.3.4 ones, which is the intent.
