feat: Voice Dev Terminal — multi-turn voice-controlled terminal via Local Link

[hassan1731996]

What This Does

A voice-native developer terminal session for OpenHome. Say "terminal", then keep talking — run git commands, check disk space, find files, tail logs — all hands-free, staying in session across multiple commands.

Why It's Unique

Every other ability in this repo is either one-shot (execute one thing, exit) or uses external APIs. This is the only ability that uses exec_local_command() via the Local Link bridge — voice → LLM-generated shell command → real terminal execution on the user's machine → spoken LLM summary of the output.

Key Differentiators vs the openhome-local-link Template

	openhome-local-link template	Voice Dev Terminal
Session	One command, exits	Stays open for multiple commands
LLM context	None — single turn	Full conversation history
Output	Raw string spoken verbatim	LLM-summarized into natural speech
Dangerous commands	No guard	Voice confirmation required
Inline trigger	No	"terminal, git status" runs immediately

UX Flow

"terminal"
→ "Terminal ready. What do you need?"

"what's my git status?"
→ "Running that now."
→ "You're on branch main, 2 files modified and not staged."

"show recent commits"
→ "Running that now."
→ "3 commits in the last day. Latest: fix auth bug, 2 hours ago."

"remove the build folder"
→ "That runs: rm -rf ./build. Confirm?"
→ [user: "yes"] → "Running that now." → "Done."

"done"
→ "Got it."

Technical Notes

• Uses exec_local_command(cmd, timeout=30.0) — requires openhome local start running on the user's machine
• LLM (sync text_to_text_response) used twice per turn: command generation + output summarization
• Conversation history passed to both LLM calls so relative references ("do it again with verbose") resolve correctly
• Danger detection: token-set intersection on {rm, rmdir, sudo, shutdown, reboot, dd, mkfs, kill, pkill}
• No persistent storage — terminal sessions are ephemeral by design
• resume_normal_flow() called in finally covering all exit paths
