## Summary
Adds a new `GET /api/v2/debug/profile` endpoint that collects multiple
pprof profiles in a single request and returns them as a tar.gz archive.
This allows collecting profiles (including block and mutex) without
requiring `CODER_PPROF_ENABLE` to be set, and without restarting
`coderd`.
Closes#21679
## What it does
The endpoint:
- Temporarily enables block and mutex profiling (normally disabled at
runtime)
- Runs CPU profile and/or trace for a configurable duration (default
10s, max 60s)
- Collects snapshot profiles (heap, allocs, block, mutex, goroutine,
threadcreate)
- Returns a tar.gz archive containing all requested `.prof` files
- Uses an atomic bool to prevent concurrent collections (returns 409
Conflict)
- Is protected by the existing debug endpoint RBAC (owner-only)
**Supported profile types:** cpu, heap, allocs, block, mutex, goroutine,
threadcreate, trace
**Query parameters:**
- `duration`: How long to run timed profiles (default: `10s`, max:
`60s`)
- `profiles`: Comma-separated list of profile types (default:
`cpu,heap,allocs,block,mutex,goroutine`)
## Additional changes
- **SDK client method** (`codersdk.Client.DebugCollectProfile`) for easy
programmatic access
- **`coder support bundle --pprof` integration**: tries the consolidated
endpoint first, falls back to individual `/debug/pprof/*` endpoints for
older servers
- **8 new tests** covering defaults, custom profiles, trace+CPU,
validation errors, authorization, and conflict detection

This flake has been persisting for a while, and unfortunately there's no
detail on which healthcheck in particular is holding things up.
This PR adds a concurrency-safe `healthcheck.Progress` and wires it
through `healthcheck.Run`. If the healthcheck times out, it will provide
information on which healthchecks are completed / running, and how long
they took / are still taking.
🤖 Claude Opus 4.5 completed the first round of this implementation,
which I then refactored.
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"
)
```

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.
Fixes https://github.com/coder/internal/issues/272
* Increases healthcheck timeout in tests. This seems to be the most
usual cause of test failures.
* Adds a non-nilness check before caching a healthcheck report.
* Modifies the HTTP response code to 503 (was 404) when no healthcheck
report is available. 503 seems to be a better indicator of the server
state in this case, whereas 404 could be misinterpreted as a typo in the
healthcheck URL.
Currently, importing `codersdk` just to interact with the API requires
importing tailscale, which causes builds to fail unless manually using
our fork.
Moves healthcheck report-related structs from coderd/healthcheck to codersdk
This prevents an import cycle when adding a codersdk.Client method to hit /api/v2/debug/health.
* 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
