Garrett Delfosse f009c17217 fix(coderd): cut DB fan-out on agent instance-identity auth (backport #24973) (#24982)
Backport of #24973 to `release/2.33`.

## Summary

Restores `v2.33.0-rc.2`-equivalent query cost for agent
instance-identity auth, which currently saturates the pgx pool when
multiple agents share an instance ID. Customer report against rc.3
traced 233x `Internal error fetching provisioner job resource` 500s
during a 50-minute incident window to this path.

## Changes

1. **System fast-path on `authorizeProvisionerJob`**
(`coderd/database/dbauthz/dbauthz.go`): Short-circuits the per-job RBAC
fan-out through `GetWorkspaceBuildByJobID` -> `GetWorkspaceByID` for
`AsSystemRestricted` callers.
2. **Drop survivor re-fetch in `handleAuthInstanceID`**
(`coderd/workspaceresourceauth.go`): Captures the provisioner job
alongside each candidate during the filter loop so the post-selection
code reads it directly instead of re-querying.

## Conflict resolution

One conflict in `coderd/database/dbauthz/dbauthz_test.go`: the
`TestAsAutostart` test function (from an unrelated commit on `main`) was
brought in as surrounding context during the cherry-pick. It was removed
since it tests functionality (`ResourceUserSecret.Read` for the
Autostart role) not present on the release branch.

## Tests

- `TestAuthorizeProvisionerJob_SystemFastPath` (3 sub-tests): all pass
- `TestPostWorkspaceAuthAWSInstanceIdentity/Ambiguous/*` (7 sub-tests):
all pass

Coder enables organizations to set up development environments in their public or private cloud infrastructure. Cloud development environments are defined with Terraform, connected through a secure high-speed Wireguard® tunnel, and automatically shut down when not used to save on costs. Coder gives engineering teams the flexibility to use the cloud for workloads most beneficial to them.

  • Define cloud development environments in Terraform
    • EC2 VMs, Kubernetes Pods, Docker Containers, etc.
  • Automatically shutdown idle resources to save on costs
  • Onboard developers in seconds instead of days

Quickstart

The most convenient way to try Coder is to install it on your local machine and experiment with provisioning cloud development environments using Docker (works on Linux, macOS, and Windows).

# First, install Coder
curl -L https://coder.com/install.sh | sh

# Start the Coder server (caches data in ~/.cache/coder)
coder server

# Navigate to http://localhost:3000 to create your initial user,
# create a Docker template and provision a workspace

Install

The easiest way to install Coder is to use our install script for Linux and macOS. For Windows, use the latest ..._installer.exe file from GitHub Releases.

curl -L https://coder.com/install.sh | sh

You can run the install script with --dry-run to see the commands that will be used to install without executing them. Run the install script with --help for additional flags.

See install for additional methods.

Once installed, you can start a production deployment with a single command:

# Automatically sets up an external access URL on *.try.coder.app
coder server

# Requires a PostgreSQL instance (version 13 or higher) and external access URL
coder server --postgres-url <url> --access-url <url>

Use coder --help to get a list of flags and environment variables. Use our install guides for a complete walkthrough.
