<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> Launches the new Copilot experience and aligns API behavior with the
UI.
>
> - **Routing/Home**: Add `/copilot` with `CopilotShell` (desktop
sidebar + mobile drawer), make homepage route flag-driven; update
login/signup/error redirects and root page to use `getHomepageRoute`.
> - **Chat UX**: Replace legacy chat with `components/contextual/Chat/*`
(new message list, bubbles, tool call/response formatting, stop button,
initial-prompt handling, refined streaming/error handling); remove old
platform chat components.
> - **Sessions**: Add paginated session list (infinite load),
auto-select/create logic, mobile/desktop navigation, and improved
session fetching/claiming guards.
> - **Auth/Logout**: New `/logout` flow with delayed redirect; gate
various queries on auth state and logout-in-progress.
> - **Backend**: `GET /api/chat/sessions/{id}` returns `null` instead of
404; service saves assistant message on `StreamFinish` to avoid loss and
prevents duplicate saves; OpenAPI updated accordingly.
> - **Misc**: Minor UI polish in library modals, loader styling, docs
(CONTRIBUTING) additions, and small formatting fixes in block docs
generator.

## Changes 🏗️
### System credentials in Run Modal
We had the issue that "system" credentials were mixed with "user"
credentials in the run agent modal:
#### Before
<img width="400" height="466" alt="Screenshot 2026-01-14 at 19 05 56"

/>
This created confusion among the users. This "system" credentials are
supplied by AutoGPT ( _most of the time_ ) and a user running an agent
should not bother with them ( _unless they want to change them_ ). For
example in this case, the credential that matters is the **Google** one
🙇🏽
### After
<img width="400" height="350" alt="Screenshot 2026-01-14 at 19 04 12"
src="https://github.com/user-attachments/assets/e2bbc015-ce4c-496c-a76f-293c01a11c6f"
/>
<img width="400" height="672" alt="Screenshot 2026-01-14 at 19 04 19"
src="https://github.com/user-attachments/assets/d704dae2-ecb2-4306-bd04-3d812fed4401"
/>
"System" credentials are collapsed by default, reducing noise in the
Task Credentials section. The user can still see and change them by
expanding the accordion.

/>
If some "system" credentials are missing, there is a red label
indicating so, it wasn't that obvious with the previous implementation,
<img width="400" height="309" alt="Screenshot 2026-01-14 at 19 04 30"
src="https://github.com/user-attachments/assets/f27081c7-40ad-4757-97b3-f29636616fc2"
/>
### New endpoint
There is a new REST endpoint, `GET /providers/system`, to list system
credential providers so it is easy to access in the Front-end to group
them together vs user ones.
### Other improvements
#### `<CredentialsInput />` refinements
<img width="715" height="200" alt="Screenshot 2026-01-14 at 19 09 31"

/>
Use a normal browser `<select>` for the Credentials Dropdown ( _when you
have more than 1 for a provider_ ). This simplifies the UI shennagians a
lot and provides a better UX in 📱 ( _eventually we should move all our
selects to the native ones as they are much better for mobile and touch
screens and less code to maintain our end_ ).
I also renamed some files for clarity and tidied up some of the existing
logic.
#### Other
- Fix **Open telemetry** warnings on the server console by making the
packages external
- Fix `require-in-the-middle` console warnings
- Prettier tidy ups
