hermes - 💡(How to fix) Fix [Bug]: Outbound MEDIA extraction misses .md/.markdown document not sent as file [1 pull requests]

Bug Description

Hermes already lists .md as a supported document type, and Telegram can send Markdown files as native document attachments. However, outbound MEDIA: delivery does not currently extract .md or .markdown paths.

When a message contains something like:

text MEDIA:/tmp/example.md

Hermes sends that line as visible text instead of uploading the Markdown file as a document attachment.

This appears to be because BasePlatformAdapter.extract_media() in gateway/platforms/base.py includes extensions such as .txt, .pdf, and .zip in its MEDIA: regex, but does not include .md or .markdown.

Adding md|markdown to the outbound MEDIA: extraction regex fixes the issue and allows Markdown files to be delivered as native document attachments.

Steps to Reproduce

1. Start a Hermes chat session with Telegram delivery available.

2. Ask Hermes to create a Markdown file, for example:

Create a small Markdown file at /tmp/hermes-media-test.md and send it to me on Telegram as an attachment.

1. Hermes creates the file and attempts to send it using an outbound MEDIA: tag similar to:

MEDIA:/tmp/hermes-media-test.md

1. Check the Telegram chat.

Expected Behavior

Hermes should recognize the .md path as a document attachment and upload the Markdown file to Telegram, the same way it handles .txt, .pdf, and .zip files.

Actual Behavior

The MEDIA:/tmp/hermes-media-test.md path appears as normal message text. No .md file attachment is uploaded.
