Test_TaskSend flaked (coder/internal#1547, coder/internal#1609) when a
stray POST /chat/completions hit the fake agent API and the catch-all
handler called t.Fatalf. No code under test posts that path to the
sidebar app URL; the request most likely came from another test's
lingering client after its server's ephemeral port was reused. Fatalf
was also called off the test goroutine, which the testing package
forbids.
Unknown paths now get a 404 and a log line with request details for
attribution. Unstubbed known agentapi endpoints still fail the test, via
t.Errorf, so a coderd regression is still caught.
These tests use dbfake to set up database state directly and don't
need a provisioner daemon. Removing it fixes a flaky failure on
Windows where the provisioner daemon acquired a job that dbfake had
already "completed", causing the task status to be "error" instead
of "paused".
Fixescoder/internal#1322
Refs coder/internal#1323
Provisioner steps broken into smaller granular actions.
Changes:
- `ExtractArchive` moved to `init` request (was in `configure`)
- Writing `tfstate` moved to `plan` (was in `configure`)
- Moved most plan/apply outputs to `GraphComplete`
## Overview
This change promotes the tasks CLI commands from `coder exp task` to
`coder task`, marking them as generally available (GA).
## Migration
Users will need to update their scripts from:
```shell
coder exp task create "my task"
```
To:
```shell
coder task create "my task"
```
