Closes#46506
Release Notes:
- Fixed an issue where the codestral URL used for credentials would be
different than the one used for requests causing authentication errors
### Summary
Adds accept/reject tracking for Mercury edit predictions.
### Changes
Sends events to https://api-feedback.inceptionlabs.ai/feedback when:
Accept — user presses Tab
Reject — user presses Escape
Ignore — prediction dismissed implicitly (typing, cursor move, etc.)
Added `discard_explicit` method to the delegate trait to distinguish
explicit vs implicit dismissal. Updated `reject_prediction` and
`reject_current_prediction` methods with an `explicit` bool parameter to
thread this through to the Mercury feedback logic. Other providers are
unaffected—they use the default implementation.
Feedback is fire-and-forget in a background thread, only sent for
predictions that were shown.
### Data Collected
- Request ID (returned from Inception API)
- User action (either accept/reject/ignore)
- Client Zed version (to track updates made to Zed client which could
potentially affect nextedit implementation)

Release Notes:
Refactored:
- Use [flake-parts](https://flake.parts/index.html) modules
- `nix/shell.nix` -> `nix/modules/devshells.nix`
Added:
- Use
[flake-parts.partitions](https://flake.parts/options/flake-parts-partitions.html)
to isolate dev dependencies so that flakes that use `zed-editor` don't
fetch dev-only inputs such as `treefmt-nix`
- [treefmt-nix](https://github.com/numtide/treefmt-nix)
- nixfmt
- rustfmt
Fixed:
- `shell.nix` and `default.nix` fetching `flake-compat` from
`flake.lock` which added an extra and unnecessary input/dependency to
`flake.nix`. Fixed by setting a fixed rev and sha256 instead.
- `nixfmt-rfc-style` is deprecated and is now `nixfmt`
- Fixes#45338 by using rust-overlay toolchain directly
- Previously, the devShell included `rustup` which caused slow startup
times as Nix would build rustup from source (including running its test
suite). Additionally, rust tooling (cargo, rustfmt, clippy,
rust-analyzer) wasn't available in the dev shell.
- cargo, rustc, and rust-toolchain.toml components included in
`rustToolchain`
Chore:
- Update `flake.lock`
- Format Rust code with `rustfmt` via `treefmt-nix`

This PR introduces support for Next Edit Suggestions while doing away
with calling legacy endpoints. In the process we've also removed support
for cycling completions, as NES will give us a single prediction, for
the most part.
Closes#30124
Release Notes:
- Zed now supports Copilot's [Next Edit
Suggestions](https://code.visualstudio.com/blogs/2025/02/12/next-edit-suggestions).
When no predictions are available for the current buffer, we will now
attempt to predict at the closest diagnostic from the cursor location
that wasn't included in the last prediction request. This enables a
commonly desired kind of far-away jump without requiring explicit model
support.
