refactor: consolidate managed configs and switch go/tool-versions to mise

Reorganize symlinked configs from .config-source to .managed directory for better clarity on auto-updated vs manual files. Add mise config.toml to replace .tool-versions, pin zoxide and deno versions. Remove Go from PATH templates since it's now managed via mise.
