Follow up to #29952

Release Notes:

- Fix an issue where zeta usage would show up when using Copilot as an
edit prediction provider

Problem Statement:
Support for image analysis (vision) is currently restricted to Anthropic
and Gemini models. This limits users who wish to leverage vision
capabilities available in other models, such as Copilot, for tasks like
attaching image context within the agent message editor.

Proposed Change:
This PR extends vision support to include Copilot models that are
already equipped with vision capabilities. This integration will allow
users within VS Code to attach and analyze images using supported
Copilot models via the agent message editor.

Scope Limitation:

This PR does not implement controls within the message editor to ensure
that image context (e.g., through copy-paste or attachment) is
exclusively enabled or prompted only when a vision-supported model is
active. Long term the message editor should have access to each models
vision capability and stop the users from attaching images by either
greying out the context saying it's not support or not work through both
copy paste and file/directory search.

Closes #30076 

Release Notes:

- Add vision support for Copilot Chat models

Release Notes:

- agent: Added a menu item in the panel's menu for the zooming in/out
feature.

As of https://github.com/zed-industries/zed/pull/30504, we now can zoom
in the whole panel, which uses the `shift-escape` keybinding. We were
also using the same binding for the message editor expansion, which was
caused a conflict. Now, the message editor expansion requires an
additional key (`alt`) to work.

Release Notes:

- agent: Fixed conflicting keybinding between message editor and panel
zoom.

I noticed the discussion in #28881, and had thought of exactly the same
a few days prior.

This implementation should preserve existing functionality fairly well.

I've added a dependency (serde_with) to allow the deserializer to skip
models which cannot be deserialized, which could occur if a future
provider, for instance, is added. Without this modification, such a
change could break all models. If extra dependencies aren't desired, a
manual implementation could be used instead.

- Closes #29369 

Release Notes:

- Dynamically detect available Copilot Chat models, including all models
with tool support

This PR updates the plan display in the user menu in the title bar to
hide plans that do not have a subscription period.

Release Notes:

- Improved the displaying of the plan in the user menu.

This PR updates the edit prediction onboarding modal with steps about
subscribing to a plan.

When the user is not subscribed to a plan, we display a link to the
account page to sign up for one:

This is my first time contributing, so happy to make changes as needed.

## Problem

I found the LLM Provider settings to be pretty difficult to scan as I
was looking to enter my API credentials for a provider. Because all of
the provider configuration is exposed by default, providers that come at
the end of the list are pushed fairly far down and require scrolling. As
this list increases the problem only get worse.

## Solution

This is strictly a UI change.

* I put each provider configuration in a Disclosure that is closed by
default. This made scanning for my provider easy, and exposing the
configuration takes a single click. No scrolling is required to see all
providers on my 956px high laptop screen.
* I also added the success checkmark to authenticated providers to make
it even easier to find them to update a key or sign out.
* The `Start New Thread` had a class applied that was overriding the
default hover behavior of other buttons, so I removed it.

Cherry-picked markdown: Fix out of range panic in parser (#30510)

For some reason `pulldown_cmark` treats \````` as a codeblock, meaning
that we could end up with an invalid range generated from
`extract_code_block_content_range` (`3..2`)

Closes https://github.com/zed-industries/zed/issues/30411

Rendering as markdown gives us text selection and copying for free. In
the future, we may want to explore having these commands be actual
editors, allowing you to step in, change the command, and re-run it
right from there.

Release Notes:

- agent: Made the terminal command in the tool card selectable and
copyable.

This reverts commit ce053c9bff0699c922e62c0b3618249e0b9801b9.

Cherry-picked Fix agent panel scroll while editing a past message
(#30394)

This is similar to the `block_mouse_down` method added in #20649 (which
has a very similar motivation), but is more comprehensive in stopping
mouse events. Since I want to cherry-pick this to the releases, keeping
this change just to the agent panel. In a follow-up will replace
existing use of `block_mouse_down` to instead use this.

This PR restores the `ContextEditor` actions that were lost in
https://github.com/zed-industries/zed/pull/30168.

Closes https://github.com/zed-industries/zed/issues/30356.

Release Notes:

- agent: Added back some missing actions, including `assistant: quote
selection`.

Release Notes:

- Fixed a race condition that sometimes prevented a system-installed
`node` binary from being detected.
- Fixed a bug where the `node.path` setting was not respected when
invoking npm.

Closes https://github.com/zed-industries/zed/issues/30238

Release Notes:

- agent: Fixed layout shift happening in the toolbar (both in the
singleton and multibuffers) due to the "Generating" label that appeared
while the agent is still generating a response.

- Try to preserve previously selected item on update
- Do not clear list items while updating to avoid a frame with no items
rendered

This reverts commit 3615d6d96c5d1c8fd0ccb1ee0bc176e9c94ac730.

Ultimately, we want to restore the ability to store a profile
per-thread, but for now reverting this fixes a fairly disruptive bug.

Release Notes:

- Fixed a bug causing the agent to use the wrong profile in some cases.

Reverts back to previous behavior where we update your settings so we
can load a new thread from your last configuration.

Release Notes:

- agent: Persist profile changes for new threads

This PR's main goal is to show the delete thread button when the list
item is either focused or hovered. In order to do that, we ended up
refactoring (i.e., merging) the `PastThread` and `PastContext` elements
into a single `HistoryElementEntry` that already matches to the entry
type (i.e., context or thread).

Release Notes:

- agent: Simplify the UI by showing the delete thread icon button only
on hover or focus.

This PR changes the way a horizontal margin is added in editors. It
removes the possibility to set a custom `horizontal_padding` for an
editor and utilizes the default `gutter_dimension` instead.

This change is made to ensure that no issues with soft-wrapping occurs
for any editor that has a `horizontal_margin` set (see #26893 for more
context on the implications here`. Furthermore, it ensures that the text
actually renders properly when scrolling horizontally and is not
cut-off.

### Horizontal padding:

|

Notice the difference at the horizontal borders.

The margin added for the `edit_file_tool` was 4 pixels. The `descent`,
whilst not exactly, is roughly the same here and also scales with the
font size nicely. Furthermore, it seems that the
`gutter_dimensions.margin` should be present anyway, given the following
comment


https://github.com/zed-industries/zed/blob/0b00256f5884fd17b4f834730b31f365613f3683/crates/editor/src/element.rs#L6887-L6889

so ensuring this property is actually set and not 0 seems to be
reasonable given the circumstances.

Please note though that this will apply to all editors in the app.
Again, this seems like it should be the case anyway, just wanted to
mention this again.

Should the fix like this not be wanted, I can change this here so that
the `horizontal_margin` is better accounted for when soft-wrapping in an
editor. Feel free to let me know in this case.

This change enables fuzzy search on model providers and names. For
example, the query "z41" will match "zed/gpt-4.1".

Release Notes:

- Agent: Improved model selection with fuzzy search support

Release Notes:

- agent: Render edit tool error as markdown and allow selecting it

We were still using entry indexes to scroll, but the list now includes
the separators as items, so the indexes need to be translated

Release Notes:

- agent: Fix autoscrolling to history entry when navigating via keyboard

Fixes an issue introduced by #29959 which caused the message editor to
overflow from the agent panel bounds, making the bottom buttons
invisible when the editor was expanded (cmd+esc).

Fixing this required changing the base structure of the agent panel, but
things seem to work as expected:

Cherry-picked Fix error when Copilot calls tools without arguments
(#30371)

Fixes https://github.com/zed-industries/zed/issues/30346

The model can output an empty string to indicate the absence of
arguments, which can't be parsed as a `serde_json::Value`. When that
happens, we now create an empty object instead on behalf of the model.

Release Notes:

- Fixed a bug that prevented Copilot models from calling the
`diagnostic` tool.
