This PR makes it so that all kinds of @-mentions start loading their
context as soon as they are confirmed. Previously, we were waiting to
load the context for file, symbol, selection, and rule mentions until
the user's message was sent. By kicking off loading immediately for
these kinds of context, we can support adding selections from unsaved
buffers, and we make the semantics of @-mentions more consistent.
Loading all kinds of context eagerly also makes it possible to simplify
the structure of the MentionSet and the code around it. Now MentionSet
is just a single hash map, all the management of creases happens in a
uniform way in `MessageEditor::confirm_completion`, and the helper
methods for loading different kinds of context are much more focused and
orthogonal.

This pull request introduces title generation and history replaying. We
still need to wire up the rest of the history but this gets us very
close. I extracted a lot of this code from `agent2-history` because that
branch was starting to get long-lived and there were lots of changes
since we started.
Release Notes:
- N/A
- Support adding ImageContent to messages through copy/paste and through
path completions
- Ensure images are fully converted to LanguageModelImageContent before
sending them to the model
- Update ACP crate to v0.0.24 to enable passing image paths through the
protocol
