feat: ship hitridge-business-o1 v0.1.0 — signed depo package + toolchain

- package: manifest v1.0 (schema, package_id, layers: odoo_modules/agents/docs/config/brain)
- agents: 4 neutral cards + prompts (sellers-recruiter, test-operator, closer, compliance)
  no script.run in v0.1.0; odoo.* + file.* primitives only
- modules: aura_business_core + hitridge_venture_o1 stubs (menus, ACLs, models)
- docs: playbook, test-checklist, price-guide-starter, agreement-template.odt
- config: channels (olx-bg/forums-local), pricing-rules (BGN, A/B/C/reject, drop ladder)
- brain: empty-seed capability contract + seeds README (memories never ship)
- toolchain: depo-sign.sh (ed25519, PEM+raw), validate-depo.sh (schema/files/cards/tools/
  secrets/sig gates -> writes VALIDATE), tool-registry.json
- install.sh: target-side verify (hash + ed25519 + layer files); install is phase 2
- public-keys/depo-signing.pub committed (private key stays out of repo)
- VALIDATE: PASS (signed + verified, tamper-rejection tested)
