banking twin: stage execution bundles for stress, capital, filing, and policy audit

Summary

This draft PR stages the first banking execution bundle tranche in agentplane.

Included in this tranche:

• banking execution bundle note under docs/
• stress-runner bundle
• capital-rollforward bundle
• filing-assembler bundle
• policy-audit bundle

Why this tranche exists

agentplane is the clean bridge from deterministic transport into governed execution with evidence and replay. This PR freezes the first banking execution lane identities and artifact directories before runtime-specific banking logic lands.

Scope boundaries

This tranche is additive only.
It does not mutate the bundle schema.
It does not yet add banking example receipts or runtime-governance integration.

Upstream dependency context

This PR is downstream of the staged banking semantic and transport work across:

• gaia-world-model
• ontogenesis
• socioprophet-standards-storage
• TriTRPC

Suggested review focus

• confirm the banking bundle names and boundaries are sensible
• confirm policy-pack refs and artifact directories are explicit
• confirm the tranche remains additive and replay/evidence-oriented
