feat: upgrade Twilio SDK to v5 and require as peer dependency

WHAT:
- Upgraded the core `twilio` Node.js helper library to v5.5.2 across
  relevant packages (`runtime-handler`, `create-twilio-function` defaults,
  test dependencies).
- Changed `@twilio-labs/serverless-runtime-types` and
  `@twilio-labs/twilio-run` to declare `twilio` as a `peerDependency`
  (^5.5.2) instead of a direct dependency.
- Updated internal type definitions (`ClientOpts`) for compatibility with
  `[email protected]`.
- Updated Twilio Console URL generation logic in `twilio-run`.
- Updated default dependencies (`typescript`, `serverlessRuntimeTypes`) used
  by `create-twilio-function`.

WHY:
- Aligns the toolkit with the latest Twilio SDK features, improvements, and
  security updates available in v5.
- Resolves potential version conflicts and type mismatches (e.g.,
  TS2322/TS2352) by ensuring a single `twilio` instance is used, managed
  explicitly by the consuming project. This promotes a more stable and
  predictable dependency graph.

BREAKING CHANGE:
Consumers of `@twilio-labs/twilio-run` or projects directly importing
types from `@twilio-labs/serverless-runtime-types` MUST now explicitly
install `twilio` as a direct dependency in their own project.

Add the `twilio` dependency:
```bash
npm install twilio@^5.5.2 --save-dev
yarn add twilio@^5.5.2 --dev
```

+feat: Upgrade Twilio SDK to v5 and use peer dependency
+
+**WHAT:**
+- Upgraded the core `twilio` Node.js helper library to v5.5.2 across the toolkit.
+- Changed `@twilio-labs/serverless-runtime-types` and `@twilio-labs/twilio-run` to require `twilio` as a `peerDependency` instead of a direct dependency.
+- Updated type definitions (`ClientOpts`) for compatibility with `[email protected]`.
+- Updated default dependencies (`twilio`, `typescript`, `serverlessRuntimeTypes`) used by `@twilio-labs/create-twilio-function`.
+
+**WHY:**
+- Aligns the toolkit with the latest Twilio SDK features, improvements, and security updates.
+- Resolves potential type conflicts (e.g., `TS2322`/`TS2352`) by ensuring a single `twilio` instance, managed by the user's project.
+
+**HOW:**
+**BREAKING CHANGE:** Users of `@twilio-labs/twilio-run` or projects importing types from `@twilio-labs/serverless-runtime-types` **must** now add `twilio` as a direct dependency to their project:
+```bash
+npm install twilio@^5.5.2
+# or
+yarn add twilio@^5.5.2
+```
+After updating toolkit packages and adding `twilio`, perform a clean install (delete `node_modules` and lock file, then run `npm install` or `yarn install`).

+**Peer Dependency Requirement:**
+
+This package requires the core `twilio` Node.js library as a **peer dependency** (version `^5.5.2` or compatible). This is necessary to ensure type consistency and prevent version conflicts within your project.
+
+**You MUST explicitly install both `@twilio-labs/serverless-runtime-types` and a compatible version of `twilio` in your project.**
+
+```bash
+# Using npm
+npm install @twilio-labs/serverless-runtime-types twilio@^5.5.2 --save-dev
+```
