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.
Refactors our use of `slogtest` to instantiate a "standard logger" across most of our tests. This standard logger incorporates https://github.com/coder/slog/pull/217 to also ignore database query canceled errors by default, which are a source of low-severity flakes.
Any test that has set non-default `slogtest.Options` is left alone. In particular, `coderdtest` defaults to ignoring all errors. We might consider revisiting that decision now that we have better tools to target the really common flaky Error logs on shutdown.
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"
```
