telegram/discord: make state dir configurable via env var

Hardcoded ~/.claude/channels/<name>/ meant only one bot per machine.
Respect TELEGRAM_STATE_DIR / DISCORD_STATE_DIR so users can run
multiple bots with separate tokens and allowlists.

Also fixed README path ('in your project' -> '~/...') to match the code.

Fixes #792
