Summary

Implements the addon side of SQI1's additive contract so members and gear-readiness info show up for guildies who are offline or have never run the addon, ahead of raids opening Dec 9:

• Item tooltips' "Crafted by" line now also lists crafters from the site's on-demand import (SideQuestDB.onDemand.crafters + recipe_names), deduplicated against live Directory.WhoCrafts hits and matched by exact recipe name.
• Item tooltips show a "Wanted by N guildies" line under the Auction house line when GameImportPrice.wanted > 0 (singular "guildie" for exactly one).
• Crafters > Professions now folds in on-demand crafters (skill + profession), marked offline like the Search tab, deduped against the live directory by character+profession. Cooldowns stay live-only (the import has none).
• Guild tab member detail shows ilvl from GameImportCharacter.item_level when the live directory hasn't scanned that character's gear; a live scan always wins.

All four fields/behaviors are additive: an import predating them (or missing them) leaves the addon working exactly as before, with no error.

Notes for reviewers

• Depends on the website adding GameImportCharacter.item_level: int | None = None and GameImportPrice.wanted: int = 0 (SQI1, additive) — tracked separately; the addon treats both as optional already.
• README updated for the Crafters tab, Guild tab detail panel, item tooltip and "What the addon shares" sections.
