v0.1.5

• Corpus opt-out (feeds.dataset_opt_out) now also covers the reader and the MCP read_post tool: an opted-out publisher's page is framed or linked to, never extracted, cached or translated.
• New operator script packages/db/src/corpus-opt-out.js; remove-feed.js --restore lifts a removal made in error.
• Fix: feed, reader, view and author pages 404'd for every non-ASCII slug (Next 16 passes page params percent-encoded).
