Enforce workspace isolation at every layer:
- Router: move RequireWorkspaceMember middleware to group level so ALL
workspace-scoped routes (issues, agents, skills, runtimes, inbox,
comments) require workspace context
- SQL: add GetXxxInWorkspace queries that filter by workspace_id,
eliminating cross-workspace data access at the query level
- Handlers: loadXForUser functions use workspace-scoped queries,
no fallback to unscoped queries
- Migration 025: add workspace_id column to comment table with backfill
- ListComments: add workspace_id filter for defense-in-depth
Fix daemon workspace mapping:
- Server returns workspace_id in task claim response (from issue)
- Daemon uses task.WorkspaceID directly instead of unreliable
workspaceIDForRuntime() local map lookup
- Remove workspaceIDForRuntime function
Fix agent/human parity:
- Comment update/delete: use resolveActor for isAuthor check so agents
can edit/delete their own comments
- Event attribution: replace hardcoded "member" with resolveActor in
agent, skill, and subscriber publish calls
