v0.12.11

Summary

• Add a shared blocked-site recovery policy across prompt variants.
• Budget blocked-site recovery to one targeted search fallback, one same-site fallback URL, and one same-site read/extract attempt.
• Remove the validation-path instruction that could force a fresh external search while finalizing.
• Tighten existing bot-block/search-fallback loop windows so blocked/search-engine tails stop earlier.
• Mark search-engine challenge responses as consuming the search fallback budget.
