[Grpc] Add gRPC data-class generation (#38)

# Description

Adds **gRPC data-class generation** to Sindri, mirroring the existing
CLI and HTTP verticals so that a `@GrpcService` app can pre-generate its
cached service map (`AppGrpcRoutingData`) exactly as it does for
HTTP/CLI routes.

Sindri reflects (via JavaParser) over `@GrpcService` controllers
reachable from a component provider's `getGrpcProviders()`, reads each
`@GrpcMethod`, and emits an `AppGrpcRoutingData implements
GrpcRoutingDataContract` whose `routes()` maps `/package.Service/Method`
to a `Supplier<RouteContract>`. The generated supplier wires the
annotated method as the reflective handler and carries the client/server
streaming flags.

Like the CLI/HTTP readers, Sindri only emits *strings* referencing
`io.valkyrja.grpc.*`, so this compiles against the current published
framework — no new dependency. (The generated output is compiled by the
app, which needs the gRPC-enabled framework release.)

## Types of changes

- [ ] Improvement _(non-breaking change which improves code)_
- [ ] Bug fix _(non-breaking change which fixes an issue)_
- [x] New feature _(non-breaking change which adds functionality)_
- [ ] Deprecation _(breaking change which removes functionality)_
- [ ] Breaking change _(fix or feature that would cause existing
functionality to change)_
- [ ] Documentation improvement

## Changes

- **`ast/data/GrpcRouteData`** (+ contract) — the parsed gRPC route data
record, paralleling `CliRouteData`/`HttpRouteData`.
- **`ast/GrpcRouteAttributeReader`** (+ contract) +
**`ast/data/result/GrpcRouteAttributeResult`** — reads
`@GrpcService`/`@GrpcMethod`, keying routes by `/service/method` with a
reflective handler supplier and streaming flags.
- **`generator/ast/grpc/AstGrpcDataFileGenerator`** (+ contract) — emits
`AppGrpcRoutingData implements GrpcRoutingDataContract`.
- **`ast/data/result/ComponentProviderResult`** +
**`ast/ComponentProviderReader`** — collect `getGrpcProviders()`
