Improve .env discovery (#737)
Resolves TOO-201

Documentation PR for this is here:
https://github.com/ArcadeAI/docs/pull/626


<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Changes how environment variables/secrets are discovered and loaded,
which can subtly alter runtime behavior depending on directory structure
and existing env vars; bounded traversal and added tests reduce but
don’t eliminate this risk.
> 
> **Overview**
> **Improves `.env` discovery across the MCP server and CLI.** Adds
`find_env_file()` (bounded by the nearest `pyproject.toml` by default)
and switches settings loading, `arcade deploy`, `arcade configure` stdio
env injection, and provider API-key resolution to use it.
> 
> Updates dev reload to also watch the discovered `.env` even when it
lives outside the current working directory, adjusts `deploy --secrets
all` to only run when a `.env` was found, and moves the minimal
scaffold’s `.env.example` to the project root with updated
tests/integration checks. Version bumps align examples and top-level
deps with `arcade-mcp-server` `1.17.4` and `arcade-mcp` `1.11.2`.
