Feat/cross program escrow dependencies

[AbuTuraab]

closes #559

Implemented explicit dependency graph support for program-escrow with status-based gating.

• Added dependency declaration/clearing APIs and read methods.
• Added dependency status registry with program-auth or admin-auth update paths.
• Enforced dependency checks before payout and release execution paths.
• Added cycle detection on dependency edge creation.
• Added dependency lifecycle events (dep_add, dep_clr, dep_sts).
• Added tests for dependency-gated release flow, failure semantics, cycle rejection, and dependency events.
