List the caller's recent operations

The caller's most recent operations, newest first, as one bounded window (limit, no offset pagination: meta.page is always 1, meta.pageSize echoes limit, meta.total is the number of rows returned and meta.hasNext is always false). Visibility is the same rule as GET /operations/{operationId}: an operation owned by a live project is visible only to a caller with a role in THAT project, a tenant/subscription-level operation (or one whose project no longer exists) to anyone reaching its tenant; on top, the caller must hold READ on the operation's resource plane (issue), so a compute-only role never sees storage operations. A bearer is confined to its home tenant. With projectId the feed is narrowed to that project (and its tenant's tenant-level operations). Validation: limit 1–100 (default 50), else 422; projectId must be reached by the caller, else 404 (unknown and unreached are indistinguishable). Async & state: Synchronous read; no state change. Errors: 401; 404 projectId not reached; 422 limit out of range; 500. Idempotency/Concurrency: Safe.
