test: cover GitOps delete paramsSchema, CCM paired filters, and harness_delete mapping

[cursor]

Description

Daily test-coverage automation run. Adds regression tests for high-risk paths from recent merges (#617, #642, #614) that were not yet covered on main.

Risky behavior now covered

• GitOps agent delete paramsSchema — agent_id is required (not resource_id); account-scoped deletes omit orgIdentifier/projectIdentifier query params
• GitOps application delete validation routing — cascade/propagation errors come from bodyBuilder, not paramsSchema, preventing mis-routed validation messages
• CCM paired-filter guard — cost_recommendation_count and cost_recommendation_stats do not send costCategoryDTOs when only cost_category is provided without cost_buckets (matches existing cost_recommendation list guard)
• CCM count API shape drift — dispatch surfaces _error when count API returns non-number data instead of silently returning { count: 0 }
• harness_delete identifier mapping — resource_id is mapped to agent_id for gitops_agent delete at the tool-handler layer

Test files added/updated

• tests/registry/gitops.test.ts — 3 new tests
• tests/registry/registry.test.ts — 3 new tests
• tests/tools/tool-handlers.test.ts — 1 new test

Why these tests materially reduce regression risk

These paths guard destructive GitOps deletes, CCM filter body construction, and the consolidated delete tool's identifier resolution — all areas where a silent regression would cause wrong API calls or misleading counts without an obvious runtime failure.

Type of Change

• Other — test coverage
