<context>
The `quotesdb` API is built with Axum + Tokio, targeting Cloudflare Workers via `workers-rs`. It serves JSON at `/api/*` endpoints and persists data to Cloudflare D1 (production) or a local SQLite file via Turso (development). Source lives in `src/bin/api/`.

Shared types and utilities are in `src/lib.rs` — code placed there must compile for both the host target and `wasm32-unknown-unknown`.

`GET /api/quotes` returns a paginated list of quotes. Query parameters:
- `page` (default 1): page number (1-indexed)
- `author`: case-insensitive author filter (partial match acceptable)
- `tag`: filter to quotes that have this tag

Response shape: `{"quotes": [...], "page": N, "total_pages": N, "total_count": N}`. Page size is 10.
</context>

<goal>
Implement the `GET /api/quotes` handler with pagination, optional author filter, and optional tag filter. Each quote in the response must include its tags (fetched from `quote_tags`). Return the pagination metadata in the response envelope.
</goal>

<constraints>
- Author filter should be case-insensitive (`LIKE lower(?)` or `COLLATE NOCASE`).
- Tag filter requires a JOIN with `quote_tags` — ensure the query doesn't return duplicate quotes when a quote has multiple tags.
- Out-of-range page numbers should return an empty `quotes` array, not a 404.
- Tags must be fetched for each returned quote — either via a JOIN or N+1 queries (N+1 is acceptable for now given small dataset size).
</constraints>

<skills>
Use `superpowers:test-driven-development` — write tests for: page=1 default, page=2 with 15 quotes, author filter, tag filter, combined filters.
Use `superpowers:verification-before-completion` before closing.
</skills>

<validation>
Run in order from the `quotesdb/` directory:

```sh
cargo fmt
cargo check
cargo clippy
cargo test
