Closes #30091
Follow-up to #29958

This PR fixes the profile menu flickering due to the documentation aside
after updating the agent dock position over the settings file.

The problem arose because the `documentation_side` could get out of sync
with the actual agent panel dock position. The `documentation_side` was
only updated whenever the user changed the agent panel position using
the UI, but not when updating the position in the settings file.

You can reproduce this easily by changing the `agent.dock` position to
the opposite site in your settings, which will make the profile menu
flicker again in some scenarios due to the de-sync.

This PR fixes this behavior by computing the position during render,
thus the actual set panel position and the documentation position can
never get out of sync

Release Notes:

- Fixed the agent profile menu flickering after updating the assistant
panel dock position in the settings.

This PR updates the copy around the Zed Pro description to be more
accurate.

Release Notes:

- agent: Updated some copy about Zed Pro in the configuration view.

Cherry-picked Avoid panic when opening thread as markdown in non-local
project (#30061)

Right now `agent: open active thread as markdown` will always panic when
you try to use it over collab or when SSH remoting. This PR makes it log
an error instead (we should follow up by restoring full remote support).

Release Notes:

- Prevented `agent: open active thread as markdown` from panicking when
used in a non-local project.

Closes #29781

Tested this with llama3, gemma3 and qwen3.

This is a breaking change, which means after adding this code changes in
future version zed we will require atleast lmstudio >= 0.3.15. For
context why it's breaking changes check out the issue: #29781.

What this doesn't try to solve is:

* Tool calling, thinking text rendering. Will raise a seperate PR for
these as those are not required in this PR to make it work.

      {
        "provider": "openai",
        "temperature": 0.5

      // To set parameters for all requests in general:

      },
      // To set parameters for a specific provider and model:
      {
        "provider": "zed.dev",
        "model": "claude-3-7-sonnet-latest",
        "temperature": 1.0

Closes #ISSUE

This PR updates #29943 to fall back to loading agent panel settings from
the old `assistant` key if the `agent` key is not present. Edits to
these settings will also target `assistant` in this situation instead of
`agent` as before.

Release Notes:

- Agent Beta: Fixed a regression that caused the agent panel not to
load, or buttons in the agent panel not to work.

The API will return a Bad Request (with no error message) when tools
were used previously in the conversation but no tools are provided as
part of a new request.

Inserting a dummy tool seems to circumvent this error.

Release Notes:

- Fixed an error that could sometimes occur when editing using Copilot
Chat.
