Table cells already containing **bold** markers got double-wrapped,
creating ****text**** which produced overlapping <b><i> tags rejected
by Telegram's HTML parser.

Telegram doesn't support HTML tables, so pipe-delimited Markdown tables
were rendered as hard-to-read plain text on mobile. This converts tables
to a vertical "Header: Value" format with bold first column before
sending to Telegram.

Port all 7 features from the Desktop long-polling Telegram channel plugin
to the Gateway webhook-based Telegram bot:
- Markdown → Telegram HTML formatting with parse-error fallback
- Text chunking for messages >4096 chars (paragraph-boundary split)
- Reply-to original message + 👀 ack reaction lifecycle
- Group chat support (mention/reply filtering, @mention stripping)
- Per-chat message serialization (prevents race conditions)
- Inbound media handling (voice/audio/photo/video/document)
with transcription (Whisper) and description (Vision API)
- Outbound file captions with HTML formatting
