* feat: add {{NO_REPLY}} silent marker for agent opt-out
Allow the agent to respond with {{NO_REPLY}} to suppress message
delivery for messages that don't warrant a reply. The marker is
checked in three places: the streaming edit guard (prefix match to
prevent partial sends), finalizeMessage(), and the post-stream
response handler.

* refactor: use <no-reply/> XML marker instead of {{NO_REPLY}}
Switch to XML-style self-closing tag for consistency with the XML
envelope format used elsewhere, and because LLMs produce well-formed
XML tags more reliably than template syntax.

* feat: add no-reply hint to group chat envelopes
Agents created outside lettabot (via ADE, Letta Cloud) won't have the
system prompt telling them about <no-reply/>. Adding the hint to group
chat envelopes makes the opt-out mechanism self-documenting.

The ^6.7.21 caret range resolves to 6.17.16 on fresh npm install, which
ships incompatible TypeScript types (no call signatures on default export).
Pins exact version and adds explicit type annotation on getMessage key param.
Also updates commands.test.ts to expect 5 commands (reset was added but
test still expected 4).
Fixes#192

keyv is a transitive dependency of Baileys via @cacheable/utils,
but since Baileys is in optionalDependencies, some npm versions
don't properly install its transitive dependencies on fresh installs.
Adding keyv as a direct dependency ensures it's always installed.
Fixes ERR_MODULE_NOT_FOUND: Cannot find package 'keyv' on fresh installs.

Adds /status, /heartbeat, /help, and /start commands to:
- Signal (was missing all commands)
- Slack (was missing all commands)
- WhatsApp (was missing all commands)
- Discord (was missing /help and /start)
Telegram already had full support.
Changes:
- Create src/core/commands.ts with shared HELP_TEXT and parseCommand()
- Add onCommand property to Signal, Slack, WhatsApp adapters
- Add command detection before onMessage in each adapter
- /help and /start are handled locally, /status and /heartbeat
delegate to onCommand callback
Fixes#91

"Consistency is the last refuge of the unimaginative." - Oscar Wilde
(But sometimes it's just good UX)
When a conversation has a stuck tool approval from a previous session,
the stream receives NO data at all (not even init). This leaves users
stuck with "(No response from agent)" and no clear path to recovery.
Changes:
- Track if stream received ANY data (not just assistant messages)
- If stream times out with zero data, assume stuck approval state
- Auto-reset conversation and notify user to try again
- Add message type counts to "no response" logs for debugging
- Fix 'system' -> 'init' type comparison (was causing TS error)
This addresses the issue reported by Signo on Discord where responses
were going to ADE instead of the channel due to stuck approvals.

"When the stream runs dry, dig a new well." - Infrastructure proverb
When conversations become corrupted on Letta Cloud, users see empty
responses with no useful error message. This adds:
1. Warning message when empty result detected:
- Logs: "Agent returned empty result with no response"
- Suggests running `lettabot reset-conversation`
2. New CLI command `lettabot reset-conversation`:
- Clears the conversationId from lettabot-agent.json
- Preserves agent and memory
- Next message creates fresh conversation
Symptoms of corrupted conversation:
- stop_reason: "error" with empty result
- Messages not appearing in agent history
- duration_api_ms: 0 (no API call made)

* Add voice message transcription support (all channels)
Adds OpenAI Whisper transcription for voice messages across all channels:
- Telegram: ctx.message.voice
- WhatsApp: audioMessage via downloadMediaMessage
- Signal: audio attachments from local files
- Slack: audio files via url_private_download
- Discord: audio attachments
Voice messages sent to agent as "[Voice message]: <transcript>"
Configuration (config takes priority over env):
- lettabot.yaml: transcription.apiKey, transcription.model
- Env: OPENAI_API_KEY, TRANSCRIPTION_MODEL
Closes#47
