Auto-detect RAILWAY_VOLUME_MOUNT_PATH and use it for all persistent data
(agent ID, cron jobs, logs). On local machines, data stays in project
directory. Template now includes volume by default.
- Add src/utils/paths.ts with getDataDir() and getWorkingDir() helpers
- Update Store, cron service, CLI tools to use data directory
- Log storage locations on startup for debugging
- Update deploy button URLs with UTM tracking

* feat: add Railway deployment support with agent auto-discovery
- Add railway.toml for build/deploy config with health checks
- Skip config file requirement when RAILWAY_ENVIRONMENT detected
- Auto-discover existing agent by name on container deploys
- Add findAgentByName() API function for agent lookup
- Add setAgentId() method to LettaBot class
- Add comprehensive Railway deployment docs
One-click deploy flow:
1. Set LETTA_API_KEY + channel tokens
2. LettaBot finds existing agent by AGENT_NAME (default: "LettaBot")
3. If not found, creates on first message
4. Subsequent deploys auto-reconnect to same agent

* Revert "fix: extract message from send_message tool call"
This reverts commit 370306e49de3728434352d2df1b78c744e888833.

Baileys/libsignal logs "Closing open session in favor of incoming
prekey bundle" and similar messages that are normal Signal Protocol
key renegotiation - not errors.
Changes:
- Remove our own crypto error logging (line 810)
- Add console filter to suppress Baileys crypto patterns:
- prekey bundle messages
- session renegotiation
- bad mac errors
- ratchet/key details
These are harmless noise that confused users into thinking
something was wrong.

When user selects "dedicated bot number" mode (selfChatMode=false),
skip the dmPolicy question and default to allowlist. Prompt for
allowed phone numbers immediately.
This is simpler and safer than pairing mode, which sends codes to
whoever messages the bot.
Users who want pairing or open mode can edit lettabot.yaml manually.
Also updates docs to reflect the new defaults.
