hermes - 💡(How to fix) Fix Feishu messages: markdown tables not rendered, making them unreadable [1 pull requests]

When Hermes sends messages to Feishu (飞书) that contain markdown tables, the tables are not rendered at all. The raw markdown pipe/pipe syntax is displayed as plain text, making tabular data extremely difficult to read.

Steps to Reproduce

1. Configure Feishu as a messaging platform in Hermes
2. Have Hermes send a message containing a markdown table, e.g.:


| Column A | Column B | Column C |
|----------|----------|----------|
| Value 1  | Value 2  | Value 3  |
| Value 4  | Value 5  | Value 6  |


3. View the message in the Feishu client

Actual Behavior

The raw markdown is displayed as-is:


| Column A | Column B | Column C |
|----------|----------|----------|
| Value 1  | Value 2  | Value 3  |


The table is not rendered into a proper table format.

Expected Behavior

The table should be rendered in a readable format. Options include:
- Converting to Feishu's native rich-text table format
- Rendering as a formatted text table (aligned columns)
- Any layout that is visually distinguishable as tabular data

Environment

- Platform: Feishu (飞书)
- Hermes version: current

Additional Context

This affects any skill or workflow that outputs structured data as markdown tables, which is a very common pattern. The current behavior forces users to mentally parse raw markdown pipe syntax, which is error-prone and defeats the purpose of structured output.
