SpaceSafeML — SB-DSL Seed

This repository contains a seed implementation of the SpaceSafeML Safety-Benchmark DSL (SB-DSL).

Contents added in this change:
- A small Python package (src/spacesafeml_certification_benchmark_and_) with a `dsl.py` module that defines core DSL models:
  - AgentCapabilities
  - SafetyPreCondition / SafetyPostCondition
  - ResourceBudgets
  - DataSharingPolicy
  - TelemetrySchema
  - Scenario
- A minimal in-repo SchemaRegistry for versioning DSL payloads
- Utilities to serialize/deserialize and compute deterministic manifest fingerprints
- Tests that validate round-trip JSON and fingerprint behavior
- `pyproject.toml` so the package builds cleanly
- `test.sh` which runs the test-suite and `python3 -m build`

This is intentionally a small, well-tested chunk (MVP step 1) to bootstrap the project. Follow-on work includes the verifier, simulation templates, ledger, and adapters.

Quick commands:
- Run tests: `bash test.sh`
- Build package: `python3 -m build`
