refactor!: files only by handle: uploads in, downloads out (D-46)
The owner (2026-10-23, via the question tool): "Uploads only"; and
before it: "What we would DEFINITELY want to avoid is passing a bunch
of BLOBs through AI context windows. That's just a pure waste." No file
passes through an agent's context, in either direction.

In: the inline arguments are gone with the 256 KiB limit (INLINE_MAX,
take_file's inline branch): content_base64 and its sha256 on
books.attach_receipt and books.file_document, w9_content_base64 and
w9_sha256 on books.set_w9, csv_text on the two CSV imports. A file comes
only by books.begin_upload and `wanderbooks upload`, named by its
upload_id; existing_attachment_id still names bytes stored already. The
five filing tools deny unknown fields, and any inline argument to any
tool is refused before it runs as an unknown argument pointing to
books.begin_upload (access log: refused inline_file).

Out: books.export (every format), books.asset_labels and
books.get_receipt view bytes hand the file over (HandedFile: download
command and expiry, D-29), as the CPA package and the W-9 do. Resource
reads stay text. A token keeps up to 64 handed files (was 16). The
access log's digest no longer exempts file bytes.

Docs: handbook files-in-out and parties-and-tins, mcp-interface.md,
rules.md, receipt-store.md, parties-and-attachments.md, plan/served.md
(D-46; the inline decisions marked superseded), STATUS.md, testing.md
(D-46: tests migrated to uploads and downloads, rewritten, removed,
added).

//! Spec-blind tests for the project tools of the books server (rules.md
//! B-37), driven through a real `wanderbooks server` as an agent reaches
//! it (common.rs).
//!
//! Expected behavior comes only from the tool descriptions and parameter /
//! result doc comments in `src/server.rs` and `src/types.rs` (the declared
//! interface, as `tools/list` serves it) and `docs/mcp-interface.md`
//! ("Tools — parties"). The harness is the minimal subset of
//! `tests/spec_mcp.rs` (copied from `tests/spec_assets.rs`): every success
//! validates against the tool's `outputSchema`, and every refusal leaves
//! `journal.jsonl` byte-identical (server invariant 2: a refused call
//! changes nothing).
