Leading @tags on any turn now route and pin: @provider pins the
backend, @model-id pins a model, @botname routes one turn (bare
@bot switches sticky), tags combine freely, @auto clears the pins,
and @path references a file by absolute path. Selections save into
the dir_defaults table keyed by directory and re-apply on next boot
there. Completion for all four kinds in the REPL (readline) and in
TUI textboxes (mentions= source on TuiTextBox/TuiPromptDialog).
Bump 1.22.0 -> 1.22.1.
Paste: enable CSI ? 2004 mode, parse ESC[200~...ESC[201~ into one
TuiPaste event routed to the focused panel, literal body, over-cap
pastes dropped whole. TextBox inserts with CR/CRLF normalized,
Terminal queues bytes to the pty, unmarked CRLF coalesces to one
Enter, idle flush no longer shreds slow pastes.
Complete: new TuiAutocomplete popup owned by TuiTextBox via
complete=, typing filters, arrows move, Enter accepts, Esc
dismisses. tui_complete_command feeds COMMANDS with HELP_TEXT
descriptions. Demo prompt dialog wired as the showcase.
