WaitBuffer is a thread-safe io.Writer that supports blocking until
accumulated output matches a substring or custom predicate. It
replaces ad-hoc safeBuffer/syncWriter types and time.Sleep-based
poll loops in tests with signal-driven waits.
- WaitFor/WaitForNth/WaitForCond for blocking on output
- Replace custom buffer types in cli/sync_test.go and
provisionersdk/agent_test.go
- Convert time.Sleep poll loops to require.Eventually/require.Never
in cli/ssh_test.go, coderd/activitybump_test.go,
coderd/workspaceagentsrpc_test.go, workspaceproxy_test.go, and
scaletest tests
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.

`bytes.Buffer` is not concurrency-safe.
`cmd` could write to the buffer concurrently while we're reading the
buffer in
```
require.Eventually(t, func() bool {
return bytes.Contains(output.Bytes(), []byte("ERROR: Downloaded agent binary returned unexpected version output"))
}, testutil.WaitShort, testutil.IntervalSlow)
```
Not sure about the `os: process already finished` flake, though.

Just upgraded to macOS 14.4 and TestAgentScript/Run fails for me with error `signal: killed`. I opened the test directory in a terminal and sure enough, when you execute the `echo` binary, it is immediately killed. The binary has no extended attributes and is byte-identical to the one in `/bin/`.
This fix uses a different strategy: instead of copying the `echo` binary from the system around, we just copy a small bash script that _calls_ the `echo` command.
* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
* chore: Add nix shell for simple development setup
This enables contributors using Nix to set up their environment with ease.
* improve nix style, flake output schema
* fix error message
* Update scripts/build_go_slim.sh

* fix: Change uses of t.Cleanup -> defer in test bodies
Mixing t.Cleanup and defer can lead to unexpected order of execution.
* fix: Ensure t.Cleanup is not aborted by require
* chore: Add helper annotations
This update exposes the workspace name and owner, and changes
authentication methods to be explicit. Implicit authentication
added unnecessary complexity and introduced inconsistency.
