Code Review
This pull request introduces automated documentation updates for the new quota_reservations table, which is a crucial addition for handling concurrent requests and preventing quota overflows. The changes are well-structured and the new schema design appears sound. My review includes a couple of suggestions to enhance the clarity of the generated documentation for the new table, primarily by adding descriptive text that explains its purpose and the roles of its columns.

The Description section for the new quota_reservations table is empty. Adding a brief explanation of the table's purpose would significantly improve the documentation's clarity, especially for new developers. You could use information from the pull request description to explain how this table helps prevent race conditions in quota management.
| Stores temporary reservations for quota-consuming operations to prevent race conditions and quota overflows from concurrent requests. A reservation is created when a job is requested and is consumed or expires after the job completes or times out. |

The Comment column is empty for all fields in the quota_reservations table. Adding comments to explain the purpose of each field would improve the documentation's clarity. Since this is auto-generated documentation, you might need to add these comments in the database schema itself so they are picked up by tbls on the next run.
For example:
job_id: "The ID of the background job (e.g., from River) that this reservation is for."reserved_amount: "The estimated quota amount reserved for the operation."expires_at: "Timestamp when the reservation becomes invalid and can be cleaned up if the job is orphaned."

Automated update of schema documentation from specvital-infra.
Generated by tbls - includes:
Triggered by: feat(db): add quota_reservations table for concurrent request handling
Concurrent requests caused race condition leading to quota overflow and server resource waste.
Existing CheckQuota only checked completed usage, ignoring estimated usage of pending jobs.
Adopted Reservation pattern: reserve estimated amount at request, charge actual amount at completion.
Rejected pre-deduction+refund due to UX complexity, Worker re-check fails "block at web level" requirement.
Added expires_at column for orphan reservation cleanup (per database-architect recommendation).
