Add get_character_from_url tool for direct URL-based fetching

MediaWiki API pipeline; non-Fandom URLs use a generic HTML scrape.

+### `get_character_from_url`
+
+Fetches character data from a specific URL you provide. Fandom wiki URLs are detected automatically and processed with the same structured extraction as `get_character`, giving richer results. Non-Fandom URLs are scraped generically.
+
+**Parameters:**
+| Name | Type | Description |
+|---|---|---|
+| `url` | string | Full URL to the character page |
+| `name` | string | Character name (optional — inferred from the page title for Fandom URLs) |
+| `franchise` | string | Franchise name (optional) |
+
+**Example prompt:**
+> Use get_character_from_url to fetch data from https://finalfantasy.fandom.com/wiki/Tifa_Lockhart
+
+**When to use instead of `get_character`:**
+- The character's wiki page isn't found by the automatic search
+- You want data from a specific page (e.g. a particular version or alternate wiki)
+- The franchise isn't in the supported list and you have a direct Fandom URL
+- You have a non-Fandom source you want to pull from
