## Problem
The chat listing endpoint (`GetChatsByOwnerID`) was using
`fetchWithPostFilter`, which fetches N rows from the database and then
filters them in Go memory using RBAC checks. This causes a pagination
bug: if the user requests `limit=25` but some rows fail the auth check,
fewer than 25 rows are returned even though more authorized rows exist
in the database. The client may incorrectly assume it has reached the
end of the list.
## Solution
Switch to the same pattern used by `GetWorkspaces`, `GetTemplates`, and
`GetUsers`: `prepareSQLFilter` + `GetAuthorized*` variant. The RBAC
filter is compiled to a SQL WHERE clause and injected into the query
before `ORDER BY`/`LIMIT`, so the database returns exactly the requested
number of authorized rows.
Additionally, `GetChatsByOwnerID` is renamed to `GetChats` with
`OwnerID` as an optional (nullable) filter parameter, matching the
`GetWorkspaces` naming convention.
## Changes
| File | Change |
|------|--------|
| `queries/chats.sql` | Renamed to `GetChats`, `owner_id` now optional
via CASE/NULL, added `-- @authorize_filter` |
| `queries.sql.go` | Renamed constant, params struct (`GetChatsParams`),
and method |
| `querier.go` | Interface method renamed |
| `modelqueries.go` | Added `chatQuerier` interface +
`GetAuthorizedChats` impl |
| `dbauthz/dbauthz.go` | `GetChats` now uses `prepareSQLFilter` instead
of `fetchWithPostFilter` |
| `dbauthz/dbauthz_test.go` | Updated tests for SQL filter pattern |
| `dbmock/dbmock.go` | Renamed + added mock for `GetAuthorizedChats` |
| `dbmetrics/querymetrics.go` | Renamed + added metrics wrapper |
| `rbac/regosql/configs.go` | Added `ChatConverter` (maps `org_owner` to
empty string literal since `chats` has no `organization_id` column) |
| `rbac/authz.go` | Added `ConfigChats()` |
| `chats.go` | Handler uses renamed method with `uuid.NullUUID` |
| `searchquery/search.go` | Updated return type |
| `gitsync/worker.go` | Updated interface and call site |
| Various test files | Updated for renamed types |
The provisioner state for a workspace build was being loaded for every
long-lived agent rpc connection. Since this state can be anywhere from
kilobytes to megabytes this can gradually cause the `coderd` memory
footprint to grow over time. It's also a lot of unnecessary allocations
for every query that fetches a workspace build since only a few callers
ever actually reference the provisioner state.
This PR removes it from the returned workspace build and adds a query to
fetch the provisioner state explicitly.
The experimental functions in `golang.org/x/exp/slices` are now
available in the standard library since Go 1.21.

Joins in fields like `username`, `avatar_url`, `organization_name`,
`template_name` to `workspaces` via a **view**.
The view must be maintained moving forward, but this prevents needing to
add RBAC permissions to fetch related workspace fields.
