Jon Chery 031887ec56 refactor(P57): contract surface redesign + rename + .yml repo-wide
Contract surface redesign:
- New top-level fields: id (3-6 char acronym → stack.name), name (full → stack.title),
  infrastructure (map keyed by module name, replaces module:)
- Drop uses: field (dead reference; version pin lives in CI workflow uses: line)
- Drop top-level module/inputs (now nested under infrastructure map)
- Per-module optional version (defaults to latest published from registry)
- Multi-module contracts: one file deploys N modules in one pipeline run,
  resource IDs namespaced with module name to avoid collisions
- stack.schema.json: add optional title field for display name

Rename:
- pipelines/deploy.yaml → pipelines/contract.yml (declarative spec, not a pipeline)
- pipelines/ci.yaml → pipelines/ci.yml
- All 44 .yaml files → .yml repo-wide (contracts, module examples, kyverno policies)
- .acdl/contract.yaml → .acdl/contract.yml

Resolver (core/contract_resolver.py):
- Rewrite resolve() to loop infrastructure map, default version to latest,
  merge module fragments into one stack with namespaced resource IDs
- _latest_version() picks highest non-deprecated from registry
- _namespace_resources() prefixes IDs + rewrites ref: expressions for multi-module
- Single-module path: unprefixed IDs (backward compatible)

Verification:
- 494 tests pass (0 contract-shape failures)
- Local E2E passes (contract → resolver → adapter → local ECS HTTP 200 → outbox)

# Pipeline
The platform runs two pipelines, both defined by declarative contracts that
are the single source of truth for the workflow files.
## CI pipeline
The CI pipeline runs on every push and pull request to `main`. It is defined
by [`pipelines/ci.yml`](https://github.com/acdl/acdl/blob/main/pipelines/ci.yml),
validated against
[`schemas/pipeline.schema.json`](https://github.com/acdl/acdl/blob/main/schemas/pipeline.schema.json).
Both platform-runner workflow files implement the same contract and are
byte-identical:
- `.github/workflows/ci.yml` — GitHub Actions (production)
Three stages run in sequence:
1. **lint**`py_compile` across the platform's Python files.
2. **test**`pytest` across the offline test suite.
3. **check-only**`run_platform.sh --check-only` (offline, no AWS).
`scripts/run_ci.sh` mirrors the CI pipeline locally so the pipeline is fully
reproducible from the shell:
```bash
bash scripts/run_ci.sh # run all 3 stages
bash scripts/run_ci.sh --quiet # suppress per-stage banners
```
## Deployment pipeline
The deployment pipeline runs when a consumer submits a contract. It is
defined by [`pipelines/contract.yml`](https://github.com/acdl/acdl/blob/main/pipelines/contract.yml),
validated against
[`schemas/deploy-pipeline.schema.json`](https://github.com/acdl/acdl/blob/main/schemas/deploy-pipeline.schema.json).
It is exposed to consumer repos as a **reusable workflow**:
- `.github/workflows/deploy.yml` — GitHub Actions (production)
A consumer repo invokes the reusable workflow via a **versioned tag**
(floating MAJOR + MINOR, e.g. `acdl/.github/workflows/deploy.yml@v1.6`).
The workflow checks out the consumer repo, then checks out the ACDL platform
repo into the runner workspace, and runs `scripts/run_platform.sh` against
the consumer's contract. The consumer never clones the platform repo or
invokes its scripts locally. See the [Consumer Guide](../consumer-guide/)
for the end-to-end happy path.

```
1. **validate-contract** — validates the contract YAML against the contract
schema. Fails fast on missing fields, unknown modules, or wrong types.
2. **resolve-stack** — the contract resolver resolves the contract to a
Target Stack instance (loads the module's pattern, expands its children,
wires the contract inputs, emits a stack JSON instance).
3. **security checks** (adapter) — security checks run on the resolved
stack before any infrastructure is planned.
4. **infrastructure plan** (adapter) — the engine adapter compiles the
stack to an infrastructure plan.
5. **policy checks** (adapter) — policy checks run on the plan. Results are
normalized to `PolicyCheckResult` records (severity, rule ID, pass/fail).
6. **confidence** — the confidence signal computes a score from 6 inputs
(policy, validation, freshness, source, history, NFRs). For `dev`, the
threshold is ≥ 0.50. If the band is `pass`, the pipeline proceeds.
7. **evidence event** — a hash-chained evidence event is written to the
audit outbox.
8. **infrastructure apply** (dev only) — the infrastructure plan is applied,
creating the resources. An evidence event for the apply is recorded.
Higher environments hold for human attestation (see
[Environments](../environments/)).
## Output streaming
`scripts/run_platform.sh` streams output by default so the user can see what
the platform is doing:
- **`--check-only`**: streams the emitted infrastructure file content.
- **`--plan-only`** and **full mode**: streams the infrastructure plan output.
- **Full mode**: prints policy-check results with severity, rule ID, and
pass/fail status.
A `--quiet` flag suppresses streaming (output to log files only).
