Fixes all our Go file imports to match the preferred spec that we've _mostly_ been using. For example:
```
import (
"context"
"time"
"github.com/prometheus/client_golang/prometheus"
"golang.org/x/xerrors"
"gopkg.in/natefinch/lumberjack.v2"
"cdr.dev/slog/v3"
"github.com/coder/coder/v2/codersdk/agentsdk"
"github.com/coder/serpent"
)
```
3 groups: standard library, 3rd partly libs, Coder libs.
This PR makes the change across the codebase. The PR in the stack above modifies our formatting to maintain this state of affairs, and is a separate PR so it's possible to review that one in detail.
Upgrades to slog v3 which includes a small, but backward incompatible API change to the acceptible call arguments when logging. This change allows us to verify via compile time type checking that arguments are correct and won't cause a panic, as was possible in slog v1, which this replaces (v2 was tagged but never used in coder/coder).
It also updates dependencies that also use slog and were updated.
I've left the `aibridge` dependency as a commit SHA, under the assumption that the team there (cc @pawbana @dannykopping ) will tag and update the dependency soon and on their own schedule.
Other dependencies, I pushed new tags.
This PR adds a fake SMTP server for scale testing. It collects emails sent during tests, which you can then check using the HTTP API.
#### Changes
- Added mock SMTP server
- Added `coder scaletest smtp` CLI command
- Implemented HTTP API endpoints to retrieve messages by email
- Added auto-purge to prevent memory issues
#### HTTP API Endpoints
- `GET /messages?email=<email>` – Get messages sent to an email address
- `POST /purge` – Clear all messages from memory
The HTTP API parses raw email messages to extract the **date**, **subject**, and **notification ID**.
Notification IDs are sent in emails like this:
```html
<p>
<a href="http://127.0.0.1:3000/settings/notifications?disabled=4e19c0ac-94e1-4532-9515-d1801aa283b2"
style="color: #2563eb; text-decoration: none;">
Stop receiving emails like this
</a>
</p>
```
#### CLI
```bash
coder scaletest smtp --host localhost --port 33199 --api-port 8080 --purge-at-count 1000
```
**Flags:**
- `--host`: Host for the mock SMTP and API server (default: localhost)
- `--port`: Port for the mock SMTP server (random if not specified)
- `--api-port`: Port for the HTTP API server (random if not specified)
- `--purge-at-count`: Max number of messages before auto-purging (default: 100000)
