v0.82.2

Continuation API simplification and policy extraction.

• Opaque cursor token replaces flow_id + state_version
• Flattened response shape: top-level work, applied_ops, work_results
• Decision/discriminator logic extracted to continuation_policy.py
• response_mode (standard/debug) controls output verbosity
• Immutable flow programs with per-tick overrides
• Dependency stamp for shallow revalidation between ticks
• Streamlined docs
