v0.4.0

• Add fully localized render-template packs for Traditional Chinese, German, Spanish, French, Japanese, Korean, and Brazilian Portuguese, selected by workspace.language_bcp47
• Move every human-language string out of the Rust code into the per-language template packs, so labels, headings, and disposition titles are translated in the templates and adding a language is just dropping a directory
• Replace the hand-coded config dispatch with agent-first-config dot-path traversal, and add a prune command, imap-archive origin provenance, attachment MIME-type detection, and pending-push counts in status and triage output
• Add archive case trash and restore commands
• Show the full product name in --help headings and generated docs while keeping the short afmail binary name in usage strings
• Resolve mailbox import rules in configured order and parse nonstandard message date headers
• Speed up the pull render cache and report render sub-stage progress
• Harden outbound push safety, support sparse config, and unify identity-config slug validation
• Upgrade the IMAP client and other dependencies
