Conversation
GetLatestWorkspaceAppStatusesByAppID returned all app statuses for a given app ID, which could be unbounded for long-running AI tasks. Only the most recent status was used, so we now: - Rename query to GetLatestWorkspaceAppStatusByAppID (singular) - Change query type from :many to :one - Add LIMIT 1 to SQL query - Update usages to handle single result instead of slice Fixes #20862 --- 🤖 PR was written by Claude Sonnet 4.5 Thinking and reviewed by a human 🏄🏻♂️.

Description
This PR fixes an issue where
GetLatestWorkspaceAppStatusesByAppIDreturned an unbounded number of rows for a given app ID, which could cause performance issues for noisy or long-running AI tasks.Changes
GetLatestWorkspaceAppStatusesByAppIDtoGetLatestWorkspaceAppStatusByAppID(singular):manyto:oneLIMIT 1to the SQL query to only fetch the most recent statuslen(latestAppStatus) == 0tolatestAppStatus.ID == uuid.NilImpact
This change reduces database query overhead for workspace app status updates, particularly for long-running AI tasks that update their status frequently. Previously, fetching the latest status would return all historical statuses; now it returns only the most recent one.
Fixes #20862
