Louis Knight-Webb e83e0ee169 MCP server expand tag (vibe-kanban) (#1458) ...

* Implementation is complete. Let me provide a summary of the changes made:

## Summary

I've implemented tag expansion for the MCP server. Here are the changes:

### Files Modified

1. **`crates/server/Cargo.toml`** - Added `regex = "1"` dependency

2. **`crates/server/src/mcp/task_server.rs`** - Three changes:
   - Added imports for `Tag` and `Regex`
   - Added `expand_tags()` helper function that:
     - Finds all `@tagname` patterns using regex `@([^\s@]+)`
     - Fetches tags from `/api/tags` endpoint
     - Replaces each `@tagname` with the tag's content
     - Returns original text if tag not found or on error
   - Updated `create_task` to expand tags in description before creating
   - Updated `update_task` to expand tags in description before updating
   - Updated tool descriptions to mention tag expansion support

### How It Works

When an AI agent calls `create_task` or `update_task` with a description containing `@tagname` (e.g., `"Please implement this feature @requirements"`), the MCP server will:

1. Parse the description for `@tagname` patterns
2. Fetch all available tags from the backend API
3. Replace each `@tagname` with the corresponding tag's `content`
4. Save the task with the expanded description

If a tag is not found, the `@tagname` is left as-is. If there's a network error, the original text is preserved to ensure task creation doesn't fail.
