Fix himalaya skill for CLI v1.2.0 (search DSL, move/copy arg order, editor traps)

[mattmezza]

The himalaya CLI is now installed at ~/.local/bin/himalaya (v1.2.0; also in Arch extra via sudo pacman -S himalaya). Config cli-configs/himalaya.toml is already in modern v1.x format — no migration needed.

skills/himalaya-email.md is written against an older himalaya and has command bugs. Update it to match v1.2.0.

Bugs to fix in the skill

• Search uses removed raw-IMAP syntax. -- "subject invoice" / -- "not flag seen" no longer work. v1.x uses a positional query DSL (no --): conditions date/before/after/from/to/subject/body/flag, operators not/and/or, order by <date|from|to|subject> [asc|desc].
  • Unread list: himalaya envelope list -a personal -o json "not flag seen"
• message move/copy arg order is reversed. Real syntax is TARGET first: himalaya message move Archives 123 (skill currently has move 123 "Archives"). -f is the SOURCE folder.
• Forward via heredoc <<< is wrong. message read/reply/forward/write/edit all open $EDITOR interactively — not automation-safe. Use the non-interactive template path piped into send.

Feature areas to cover (verified commands)

• Read single: himalaya message read -a personal 123 (auto-marks Seen; -p/--preview to avoid)
• Mark read/unread: flag add 123 Seen / flag remove 123 Seen
• Delete single: message delete 123 (moves to Trash)
• Mark spam: no spam flag — message move Spam 123 (run folder list for exact name)
• Unread list: envelope list -o json "not flag seen"
• Search: query DSL above
• Reply (+ reply-all -A): himalaya template reply -a personal -A 123 "body" | himalaya template send -a personal
• Send new: printf 'From:...\nTo:...\nSubject:...\n\nbody\n' | himalaya message send -a personal
• Forward: himalaya template forward -a personal 123 "FYI" | himalaya template send -a personal

Also check

• Config inconsistency: IMAP auth reads $MAIL_MEROLA_CO_APP_PASSWORD, SMTP reads $HIMALAYA_PERSONAL_PASSWORD — confirm both env vars are set or sending breaks.
