Paul Kloppers f1d4fb596a feat(redstone): wiki_recipe tool — extract recipe + thumbnail in one call ...

Adds a new MCP tool that parses minecraft.wiki's <table data-description=
"Crafting recipes"> directly, pulling the ingredients column out of each
row (e.g. "Block of Iron + Iron Ingot" for Anvil), then chases up the
page's main item thumbnail via prop=pageimages so the bot can deliver
text + a real image in one tool round.

Why a dedicated tool: minecraft.wiki does not host standalone "recipe.png"
files — recipes are rendered live as HTML grids composed from individual
BlockSprite icons. Filtering wiki_page_images for 'recipe' / 'craft' /
'grid' returned empty for every craftable item, leaving the model with
nothing to call tg_send_photo with. Confirmed by inspecting the Anvil
page's image inventory (Anvil1-6.png + GUI + sound files, no recipe).

Tool returns {
  title, page_url,
  recipes: [{ ingredients: "…" }, …],   // strips <br>/<a>/&nbsp; cleanly
  thumbnail_url,                          // for tg_send_photo
  note?,                                  // present when no recipe rows
}

Persona prompt tightened:
- wiki_recipe is now the FIRST call for "how do I craft X" / "recipe for X"
- wiki_page_images is downgraded to "specific non-thumbnail images only"
- IMAGE DELIVERY MANDATORY clause: must end the turn with tg_send_photo
  using a real URL or say plainly that no thumbnail was found — no more
  describing-the-image-in-prose-and-stopping failures.
