- Add parsing of paste to attach real files already merged
- Keep submitted image placeholders visible in history via new_user_prompt_with_images
- Plumb placeholder strings through BottomPane -> ChatWidget on submit
- Keep agent input free of placeholders (send images as LocalImage)
- Prevents the % left indicator from immediately decrementing to ~97%.
- Tested by prompting "hi" and noting it only decremented to 99%. And by
adding a bunch of debug logs and observing numbers.
This improves handling of pasted content in the textarea. It's no longer
possible to partially delete a placeholder (e.g. by ^W or ^D), nor is it
possible to place the cursor inside a placeholder. Also, we now render
placeholders in a different color to make them more clearly
differentiated.

- I had a recent conversation where the one-liner showed using 11M
tokens! But looking into it 10M were cached. So I looked into it and I
think we had a regression here. ->
- Use blended total tokens for chat composer usage display
- Compute remaining context using tokens_in_context_window helper

This will make @ more discoverable (even though it is currently not
super useful, IMO it should be used to bring files into context from
outside CWD)

Cursor wasn't moving when inserting a file, resulting in being not at
the end of the filename when inserting the file.
This fixes it by moving the cursor to the end of the file + one trailing
space.

This replaces tui-textarea with a custom textarea component.
Key differences:
1. wrapped lines
2. better unicode handling
3. uses the native terminal cursor
This should perhaps be spun out into its own separate crate at some
point, but for now it's convenient to have it in-tree.
Simplify and improve many UI elements.
* Remove all-around borders in most places. These interact badly with
terminal resizing and look heavy. Prefer left-side-only borders.
* Make the viewport adjust to the size of its contents.
* <kbd>/</kbd> and <kbd>@</kbd> autocomplete boxes appear below the
prompt, instead of above it.
* Restyle the keyboard shortcut hints & move them to the left.
* Restyle the approval dialog.
* Use synchronized rendering to avoid flashing during rerenders.

Proof of concept for a resizable viewport.
The general approach here is to duplicate the `Terminal` struct from
ratatui, but with our own logic. This is a "light fork" in that we are
still using all the base ratatui functions (`Buffer`, `Widget` and so
on), but we're doing our own bookkeeping at the top level to determine
where to draw everything.
This approach could use improvement—e.g, when the window is resized to a
smaller size, if the UI wraps, we don't correctly clear out the
artifacts from wrapping. This is possible with a little work (i.e.
tracking what parts of our UI would have been wrapped), but this
behavior is at least at par with the existing behavior.

[discussion](https://github.com/rhysd/tui-textarea/issues/51#issuecomment-3021191712),
it's surprising that ^U behaves this way. IMO the undo/redo
functionality in tui-textarea isn't good enough to be worth preserving,
but if we do bring it back it should probably be on C-z / C-S-z / C-y.
