PUT /workspaces/:id/files and DELETE /workspaces/:id/files updated the
config volume but never restarted the container, so the running agent
continued serving stale file content from its in-memory cache. The
SecretsHandler already had this pattern (issue #15); TemplatesHandler
was missing it.
Fix: after every successful write/delete in WriteFile, DeleteFile, and
ReplaceFiles, call h.wh.RestartByID(workspaceID) asynchronously, guarded
by h.wh != nil (nil-tolerant for callers that only use read-only
surfaces). The RestartByID coalescing gate prevents thundering-herd on
concurrent requests.
Fixes#151.
Fixes#87 (duplicate effort closed — core-be also filed #183).
