* fix(tui): preserve multiline pasted input The TUI composer used a single-line `Input`, so a bracketed paste containing code, a stack trace, or multiple paragraphs kept only the first line when submitted. The composer is now a multiline `TextArea`: Enter still submits, Up/Down move inside the document before falling back to input history at the first/last line, and the slash palette is unchanged. Originally #4630 by @felix-windsor, cherry-picked onto current main; conflicts in app.py key gating (transcript paging keys), test imports, and the relocated TUI docs were resolved by hand. Fixes #4613 * fix(tui): submit multiline input unchanged and document the widgets layer Address the review on #4630: - Send non-command input to the agent and history exactly as typed or pasted. Only the empty-input check uses strip(), so leading indentation and trailing newlines in pasted code and stack traces survive. Slash commands are still trimmed so they resolve as before. - widgets/composer.py imports Textual, so the module-layout notes in tui/AGENTS.md and docs/TUI.md now exempt widgets/ alongside app.py. - Cover pressing Down on the last document line (history fallback), whitespace-only input, and slash commands with surrounding whitespace.

The history fallback only looked at logical rows, so Up from the second visual row of a long prompt recalled history instead of moving the cursor, and Down from its first visual row could replace the draft with history's empty value. Use the TextArea navigator's first/last wrapped-row checks for the boundaries, and cover wrapped prompts in both directions. Also restore a tui/AGENTS.md sentence about PageUp/PageDown to the app.py entry it belongs to.
