ProductLogBeta

This update ships the first batch of improvements based on community feedback.

Added

• Markdown paste — paste markdown into any editor on ProductLog (updates, comments, feedback, stories) and it
  converts to rich formatting: headings, lists, links, bold and code blocks. Copies from terminals and VS Code are
  handled smartly.

• Keep a Changelog status tags — changelog updates now follow the Keep a Changelog convention: Added, Changed, Deprecated, Removed, Fixed and Security. Tag a release with as many as apply.

• More platforms & custom platform labels — adds CLI, Browser Extension and Plugin, and you can type your own  (LLM model, Figma plugin, anything) via the new Add Platform picker.

• Link feedback to multiple roadmap items — the same feedback can now be promoted into more than one roadmap  item, and you can unlink any of them later.

• Promote into an existing roadmap item — when promoting feedback you can attach it to an existing item
   instead of always creating a new one (with search and a recent-items shortcut).

• Link feedback straight from the roadmap — open a roadmap item, search your feedback, and attach (or re-link)
   it right there.

• Mark duplicate feedback — when the same request comes in twice, mark it as a duplicate of the original. It links to the canonical request, mirrors its roadmap status, and locks voting/comments so everyone follows progress  in one place.

Changed

• Status tags and platforms in the changelog editor are now stacked vertically instead of a cramped two-column
  layout.

• Existing "New" and "Improved" tags now display as "Added" and "Changed" — your data is untouched.
