test: cover schema sync additions from PR #584 and #567

[cursor]

Description

Adds regression tests for upstream Harness schema definitions introduced by the auto-sync workflow in PR #584 (chore/sync-schemas) and PR #567.

Risky behavior now covered

• DeployAwsAgentCoreRevision — new CD step type bundled in v0 pipeline/template schemas; agents rely on harness_schema path resolution to discover step fields (connectorRef, waitReady, etc.)
• IdentitiesConfig / IdentitySpec — OIDC identity map types and the identities field on ShellScriptStepNode; incorrect sync would break pipeline authoring for federated identity steps
• skipPipelineVariables — new field on UpdateReleaseRepoStepInfo; missing from bundle would silently drop GitOps PR variable behavior from schema discovery
• DynamicStageNodeV1 — new v1 unified stage for inline/remote child pipelines; path resolution must resolve under stages.unified

Test files added/updated

• tests/schemas/schema-bundle-contract.test.ts — structural contract assertions on bundled schema modules
• tests/tools/harness-schema-tool.test.ts — harness_schema path-resolution integration tests for DeployAwsAgentCoreRevisionStepNode, IdentitiesConfig, and DynamicStageNodeV1

Why these tests materially reduce regression risk

Auto-sync PRs are data-only and merge frequently with no production code changes. Without contract tests, a bad sync (truncated file, dropped namespace rewrite, or missing step group) would only surface when an agent calls harness_schema at runtime. These tests fail fast in CI on every PR, matching the established pattern for prior sync additions (K8sProgressiveCanaryRollback, DeployGoogleAgentRuntimeRevision).
