We currently call GetWorkspaceAgentByID millions of times at scale
unnecessarily. This PR embeds immutable fields into the relevant
services instead of fetching for them every time.
resolves https://github.com/coder/scaletest/issues/84
Confirmed with a 10k scaletest that this changeset takes the query from
10M+ queries down to 39k

This moves updating app status (used by Tasks) into the workspace agent
API over dRPC. This will allow us to update the status without having to
re-authenticate each time, like we would with an HTTP PATCH request.
Further PRs in this stack will pipe these requests thru from the CLI MCP
server to the agentsock and finally to this dRPC call to coderd.
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.
We currently send empty payloads to pubsub channels of the form `workspace:<workspace_id>` to notify listeners of updates to workspaces (such as for refreshing the workspace dashboard).
To support https://github.com/coder/coder/issues/14716, we'll instead send `WorkspaceEvent` payloads to pubsub channels of the form `workspace_owner:<owner_id>`. This enables a listener to receive events for all workspaces owned by a user.
This PR replaces the usage of the old channels without modifying any existing behaviors.
```
type WorkspaceEvent struct {
Kind WorkspaceEventKind `json:"kind"`
WorkspaceID uuid.UUID `json:"workspace_id" format:"uuid"`
// AgentID is only set for WorkspaceEventKindAgent* events
// (excluding AgentTimeout)
AgentID *uuid.UUID `json:"agent_id,omitempty" format:"uuid"`
}
```
We've defined `WorkspaceEventKind`s based on how the old channel was used, but it's not yet necessary to inspect the types of any of the events, as the existing listeners are designed to fire off any of them.
```
WorkspaceEventKindStateChange WorkspaceEventKind = "state_change"
WorkspaceEventKindStatsUpdate WorkspaceEventKind = "stats_update"
WorkspaceEventKindMetadataUpdate WorkspaceEventKind = "mtd_update"
WorkspaceEventKindAppHealthUpdate WorkspaceEventKind = "app_health"
WorkspaceEventKindAgentLifecycleUpdate WorkspaceEventKind = "agt_lifecycle_update"
WorkspaceEventKindAgentLogsUpdate WorkspaceEventKind = "agt_logs_update"
WorkspaceEventKindAgentConnectionUpdate WorkspaceEventKind = "agt_connection_update"
WorkspaceEventKindAgentLogsOverflow WorkspaceEventKind = "agt_logs_overflow"
WorkspaceEventKindAgentTimeout WorkspaceEventKind = "agt_timeout"
```
