feat: Rust yrs core with ops, view and wazero host

The Slides core, following Docs' pattern: a yrs CRDT compiled to
wasm32-unknown-unknown with zero host imports, run under wazero.

core/ (slides-core): the deck schema over yrs (schema.rs), the §7.2
operations applied as one batch in one transaction with a dry-run
model so a failure applies nothing (ops.rs), the JSON view (view.rs),
the Markdown subset ops accept text in (markdown.rs), and the C ABI
with Docs' bounds-checking and no-borrow-across-yrs rules (abi.rs).
The core never draws entropy: every id arrives from the host.

internal/core: the wazero host copied from Docs (trap containment,
rebuild by log replay, Recovered/Rejected) with State, JSON and Ops;
an Ops refusal is a *RejectedError carrying the core's message, and
the update Ops produces is retained for rebuilds.

Vendored fastrand patch, .cargo/config.toml, clippy.toml, the
reproducible build script and toolchain pin are Docs' with the
rename. The committed testdata/slides_core.wasm is byte-identical to
a fresh scripts/build-wasm.sh output.
