Add output of /auto to assistant panel

Bumping the image crate for better support of image formats.

The latest version does not have a `BGRA` type it only has `RGBA` it
doesn't really matter as the size is the same but the type name is a
little confusing as we need it as `BGRA`. Also there is no `into_bgra8`
but we can use `into_rgba8` but then it must be converted before
creating the `ImageData`.

-# This config is different from config.toml in this directory, as the latter is recognized by Cargo.
-# This file is placed in $HOME/.cargo/config.toml on CI runs. Cargo then merges Zeds .cargo/config.toml with $HOME/.cargo/config.toml
-# with preference for settings from Zeds config.toml.
-# TL;DR: If a value is set in both ci-config.toml and config.toml, config.toml value takes precedence.
-# Arrays are merged together though. See: https://doc.rust-lang.org/cargo/reference/config.html#hierarchical-structure
-# The intent for this file is to configure CI build process with a divergance from Zed developers experience; for example, in this config file
-# we use `-D warnings` for rustflags (which makes compilation fail in presence of warnings during build process). Placing that in developers `config.toml`
-# would be incovenient.
-# We *could* override things like RUSTFLAGS manually by setting them as environment variables, but that is less DRY; worse yet, if you forget to set proper environment variables
-# in one spot, that's going to trigger a rebuild of all of the artifacts. Using ci-config.toml we can define these overrides for CI in one spot and not worry about it.

+the project. It will tell you which files this string
+(or similar strings; it is a semantic search) appear in,
+as well as some context of the lines surrounding each result.
+
+---
+
+That was the end of the list of actions.
+
+Here is an XML summary of each of the files in my project:
+"#;
+
+const PROMPT_INSTRUCTIONS_AFTER_SUMMARY: &str = r#"
+Actions have a cost, so only include actions that you think
+will be helpful to you in doing a great job answering the
+prompt in the future.
+
+You must respond ONLY with a list of actions you would like to
+perform. Each action should be on its own line, and followed by a space and then its parameter.
+
+Actions can be performed more than once with different parameters.
+Here is an example valid response:
+
+```
+file path/to/my/file.txt
+file path/to/another/file.txt
+search something to search for
+search something else to search for
+```
+
+Once again, do not forget: you must respond ONLY in the format of
+one action per line, and the action name should be followed by
+its parameter. Your response must not include anything other
+than a list of actions, with one action per line, in this format.
+It is extremely important that you do not deviate from this format even slightly!
+
+This is the end of my instructions for how to respond. The rest is the prompt:
+"#;
+
+const SUMMARY: &str = "";
+
+fn chunked_line(wip: &mut String, chunk: &str, mut on_line_end: impl FnMut(&str)) {
+    // The first iteration of the loop should just push to wip
+    // and nothing else. We only push what we encountered in
+    // previous iterations of the loop.
+    //
+    // This correctly handles both the scenario where no
+    // newlines are encountered (the loop will only run once,
+    // and so will only push to wip), as well as the scenario
+    // where the chunk contains at least one newline but

+            // Since this isn't the first iteration of the loop, we definitely hit a newline
+            // at the end of the previous iteration! Run the function on whatever wip we have.
+            on_line_end(wip);
+            wip.clear();
+        }
+
+        wip.push_str(line);
+    }
