First, a new option \`cider-use-completing-read-for-symbol\` routes symbol prompts through \`completing-read\`, enabling modern completion UIs like Vertico, Ivy, and Helm to work with REPL-backed candidates that include type and namespace metadata. Second, completion annotations now align in a proper column via \`affixation-function\`, improving readability across supported frontends like Corfu and Vertico. Both changes are available in the latest CIDER MELPA build and will ship in the next stable release.
