Asher Morse 6b76ea4707 fix(gateway): load reply_to_mode from config.yaml for Discord and Telegram
The YAML-to-env-var bridge in load_gateway_config() mapped every Discord
and Telegram config key (require_mention, auto_thread, reactions, etc.)
except reply_to_mode. Users setting discord.reply_to_mode or
telegram.reply_to_mode in ~/.hermes/config.yaml got no effect — the
adapter only read the env var, which nothing populated from YAML.

Add the missing bridge for both platforms, following the existing pattern.
Top-level <platform>.reply_to_mode preferred, falls back to
<platform>.extra.reply_to_mode, env var never overwritten. Handles YAML
1.1 bare `off` → Python False coercion.

This is a re-submission of the work from #9837 and #13930, which both
implemented the same fix but neither landed (see co-authors below).

"""Tests for Discord reply_to_mode functionality.
Covers the threading behavior control for multi-chunk replies:
- "off": Never reply-reference to original message
- "first": Only first chunk uses reply reference (default)
- "all": All chunks reply-reference the original message
Also covers reply_to_text extraction from incoming messages.
