ratatui-0-24-to-0-30

Automate the most common deterministic API renames in the ratatui TUI library migration from v0.24–v0.30.

What it does

Update ratatui = "0.2x.x" → ratatui = "0.30.0"
Update ratatui = { version = "0.2x.x", ... } → ratatui = { version = "0.30.0", ... }

use ratatui::terminal::{Terminal, Frame, ...} → use ratatui::{Terminal, Frame, ...}
use ratatui::widgets::block::{Title, Position} → use ratatui::widgets::TitlePosition (Title removed)
use ratatui::widgets::block::BlockExt → use ratatui::widgets::BlockExt
use ratatui::widgets::scrollbar::{Scrollbar, Set} → split into widget/symbols imports

frame.size() → frame.area() (v0.28)
Table::highlight_style(...) → Table::row_highlight_style(...) (v0.29)
.title_on_bottom() → .title_bottom() (v0.27)
BorderType::line_symbols(...) → BorderType::border_symbols(...) (v0.24)
.track_symbol("|") → .track_symbol(Some("|")) (v0.23)

.inner(&Margin{...}) → .inner(Margin{...}) (v0.27)
Buffer::filled(area, &Cell::new(...)) → Buffer::filled(area, Cell::new(...)) (v0.27)

bash

After running, you should:

Update Cargo.toml to ratatui = "0.30.0" and review feature flags
Clean up Title alignment/position chaining: .alignment(Alignment::Center) → .centered(), .position(TitlePosition::Bottom) → title_bottom()
Handle Flex::SpaceAround → Flex::SpaceEvenly if using the old behavior
Review Backend trait implementations for the new Error associated type and clear_region method
Handle Marker exhaustive match additions (add wildcard arm)
Run cargo check and cargo test
