Greptile Summary

Fixes a bug where editing subblocks on locked agent blocks caused the socket to enter offline mode. The root cause was that flushSubblockUpdate treated a locked-block early return the same as a "block not found" case — both fell into the else branch that emitted operation-failed with retryable: false, which triggered triggerOfflineMode() on the client after exhausting retries.

• Socket handler (subblocks.ts): Introduces a blockLocked flag set during the database transaction when a block (or its parent) is locked. After the transaction, a new else if (blockLocked) branch emits operation-confirmed instead of operation-failed, acknowledging the operation without persisting changes.
• Editor UI (editor.tsx): Adds a static "Additional fields" divider for locked blocks when advanced fields with values are displayed (!canEditBlock && displayAdvancedOptions), matching the spacing of the editable-block toggle divider.

Confidence Score: 4/5

• This PR is safe to merge — it fixes a clear socket crash path with minimal, well-scoped changes.
• The socket handler fix is logically sound: blockLocked and updateSuccessful are mutually exclusive flags with clear branching. The editor UI change uses mutually exclusive conditions (canEditBlock vs !canEditBlock) preventing double-render. The only reason this isn't a 5 is the lack of automated tests — the PR notes manual testing only, and the operation queue's offline-mode triggering path is critical enough to warrant test coverage.
• No files require special attention — both changes are straightforward and low risk.
