refactor(md): Add `indent` to buffer events and list streaming (#657)

The `Event` enum variants have been converted from tuple structs to
named-field structs, each gaining an `indent: usize` field that carries
the visual column at which the renderer should place the content. For
example, `Event::Block(String)` becomes `Event::Block { content: String,
indent: usize }`.

A new `InList` buffer state replaces the old ad-hoc list-streaming logic
inside `handle_buffering_paragraph`. It tracks `marker_column`,
`content_column`, ordering, delimiter, and item count, and pushes/pops a
parent-state stack when entering nested containers (sub-lists or fenced
code blocks inside list items). Each sibling marker triggers an
immediate flush of the preceding item as a `Block` with the list's
`marker_column` as its visual indent, so items stream individually
rather than buffering the whole list.

The `Buffer::flush() -> Option<String>` API is replaced by
`flush_events() -> Vec<Event>`, which correctly splits any queued items
at sibling-marker boundaries, renumbers ordered-list markers relative to
`start_number + items_flushed`, and emits the final partial segment as a
`Flush` event with the right indent.

`TerminalOptions` gains an `indent` field, threaded through
`Formatter::format_terminal_with`, `TerminalWriter::new`, and the chat
renderer's `print_block` / `print_code` / `terminal_options` helpers.
`TerminalWriter` seeds its initial `prefix` with `indent` spaces so
every rendered line starts at the requested visual column. A new
`indent_lines` helper in the chat renderer prepends the indent to raw
code-block lines that have already been highlighted.

The practical effect: when an LLM streams a response with nested lists
or fenced code blocks inside list items, each item and code line now
renders at the correct visual column as it arrives, rather than being
buffered until the whole list is received or rendered at column 0.
