v0.34.0

Syncs the Elixir port to Python guava-sdk 0.34.0 (covering upstream 0.33.0 and 0.34.0).

Wire protocol

• Guava.Events.BotSessionEnded gains a dnc (do-not-call) boolean field on the bot-session-ended event. Defaults to false; decoded from the wire and available to handle_session_end/3.

Already covered (no change needed)

• Python's new public Agent.roleplay() maps to the existing Guava.Testing.roleplay/3.
• Python's new public helpers.llm.generate() maps to the existing Guava.LLM.generate/3.

Housekeeping

• Package version bumped 0.32.0 → 0.34.0 (mirrors the tracked Python version).
• Wire fixtures regenerated from guava-sdk 0.34.0; parity metadata updated.

Full parity notes: see PARITY.md.
