feat(welcome): parallel template messages with LLM inference for fast…

[M3gA-Mind]

Summary

• Immediate feedback: Template 1 (time-of-day greeting + connected channels) fires at t≈0ms, before the LLM starts, so the chat bubble is never blank after the wizard closes
• Loading indicator: Template 2 ("Getting everything ready for you...") publishes at t=4s via tokio::join!, running in parallel with LLM inference rather than blocking it
• No duplicate greeting: The prompt passed to run_single explicitly tells the agent that both templates have already been shown and to open directly with the personalised setup summary
• Prompt.md updated: New "Proactive invocation" section documents the three-message flow and adds a "What NOT to do" bullet blocking redundant openers

Changed files

File	Change
src/openhuman/agent/welcome_proactive.rs	Rewrote run_proactive_welcome to publish 3 events; added time_of_day_greeting() and build_template_greeting() helpers
src/openhuman/agent/agents/welcome/prompt.md	Added proactive-invocation section + "no greeting" bullet in What NOT to do

Test plan

• cargo test -p openhuman welcome_proactive — 7 unit tests cover greeting text for 0, 1, 2, 3 channels and the missing-key fallback
• cargo check passes clean; cargo fmt --check passes
• All pre-push hooks pass (Prettier, ESLint, tsc, cargo check)
• Manual smoke test: complete desktop onboarding wizard → observe three sequential chat bubbles (greeting, loading, LLM response) with no duplicate greeting in the third message
