Release v0.5.0

Prompter's answers are shorter and cheaper, it shows where its sources come from, and maintainers get new ways to hear about gaps in the docs and the platform.

Added

• Answer channel questions in a thread, configurable per channel and off by default. (#63)
• Add an "Ask a human" button that mentions a configured maintainer role with a short summary of the question, once per conversation. (#64)
• Post a weekly docs-gap digest to a configured maintainer channel, with per-product counts of docs gaps, possible missing capabilities, likely bugs and thumbs-down answers. Add "This should be documented" and "Request this" buttons that forward the question to maintainers at the asker's request, without storing it. (#65)
• Show when each cited documentation page was indexed, and its product version when the page states one. (#66)
• Link up to three related public GitHub issues under an answer when the question names a Cratis product. (part of #49)
• Classify each interaction as answered, docs gap, missing capability, likely bug or out of scope, with the product it concerns, storing only those labels.

Changed

• Generate answers with Claude Haiku 5.5 and keep them short, leading with the direct answer and linking to the cited pages for detail. (#62)
• Reindex production on a daily schedule, re-embedding only changed pages within the existing spend caps. (#67)
• Build the container image faster by cross-compiling for arm64 instead of emulating it, and cache image layers between builds.

Security

• Prevent answers and forwarded text from mentioning users, roles, @everyone or @here.
