feat(sidecar): ForstError hierarchy, dev HTTP contract tests, RFC doc renames

Harden `forst dev` against the JSON contract: method-not-allowed and error paths
use the same JSON envelope as sendError; `/types` no longer advertises a raw
TypeScript attachment. Add `dev_server_contract_test.go` for GET /health, 405
bodies, and GET /types.

Replace ad-hoc `throw new Error` in the sidecar with `ForstError` subclasses
(client HTTP, compiler download, spawned commands, and `ForstServer` startup /
shutdown / health). Export them from the package so callers can use instanceof.

Rename TypeScript client RFC files to `02-forst-dev-http-contract.md` and
`03-forst-generate-contract.md`, update links, and describe profiles without
Layer A/B labels.

Example:

```typescript
import { DevServerHttpFailure, ForstError } from "@forst/sidecar";

try {
  await client.invokeFunction("echo", "Echo", [{ message: "hi" }]);
} catch (e) {
  if (e instanceof DevServerHttpFailure) console.error(e.status, e.responseText);
  else if (e instanceof ForstError) console.error(e.message);
}
```
