Reset Open CoT RFC core around cognitive interfaces

[supernovae]

Summary

This PR performs the compact Open CoT core reset after #58:

• reframes Open CoT as the Cognitive Operations Theory interface layer
• replaces the 53 active RFC surface with 12 sequential core RFCs
• embeds normative JSON Schemas directly in each RFC using opencot:schema markers
• regenerates schemas/*.json and schemas/registry.json from those RFC blocks
• bumps the schema registry to 2.0 as an intentional hard reset
• removes retired schema/example/conformance surfaces from the core repository
• updates conformance to a single profile_core fixture matrix
• updates the reference validators and TypeScript harness schema comments to target the cognitive pipeline contract

Core RFC Set

1. Cognitive Artifact
2. Capability Snapshot
3. Execution Intent
4. Policy Gate
5. Observation Receipt
6. Reconciliation Result
7. Cognitive Pipeline
8. Execution Budget
9. Requester Identity
10. Human Approval
11. Conformance Registry
12. Compact Context

Tooling Changes

• tools/sync_schemas_from_rfcs.py now requires every active RFC to carry an explicit schema block.
• tools/schema_lib.py now maps only the 12 core RFCs.
• tools/validate.py validates the compact core examples and conformance profile.
• tools/check_conformance_fixtures.py now validates fixtures with a ref-aware schema registry.
• tools/diff_checker.py treats a registry major-version bump as an intentional compatibility reset for strict checks.
