seedInitialMemories() in workspace_provision.go was inserting template/config
memories directly into agent_memories without scrubbing credential patterns.
A workspace provisioned from a template containing API keys, tokens, or other
secrets would store them in plain text — the same class of issue as #838.
Fix: call redactSecrets(workspaceID, content) on the truncated memory content
before the INSERT. The truncation (maxMemoryContentLength = 100 KiB, CWE-400)
is preserved — redaction runs after truncation so the size limit still applies.
