Supply-chain hardening and unpublished writr-rs fixes; JS engine source is unchanged.

• restore writr-rs goldens on Windows CRLF checkouts — unify CR/CRLF to LF before parse so markdown-rs does not keep CR in mdast text (#516)
• copy async batch buffer input so callers can reuse the packed buffer after renderBatchBufferAsync (#540)
• lock down the Node WASI loader: instantiate WASI with preview1 only (no process.env, no filesystem preopens) (#545)

Widens engines.node to allow Node 24+; adds the unpublished writr-rs Rust engine workspace.

• allow Node 24+ in engines.node — ^22.18.0 resolves to >=22.18.0 <23.0.0, excluding the Node versions writr is tested on, so installs under engine-strict=true aborted with ERR_PNPM_UNSUPPORTED_ENGINE (cf8efa4, #488)

Dependency maintenance sweep: refresh dev and runtime dependencies — including the AI SDK (v7) and js-yaml (v5) majors — with no changes to writr's own API.

• upgrade code quality dependencies — biome 2.5.3, vitest & coverage-v8 4.1.10 (9eec344, #472)
• upgrade TypeScript & build tooling — tsx 4.23.0, tsdown 0.22.5, @types/node 24.13.3 (311a4e6, #473)
• upgrade GitHub Actions majors — checkout v7, setup-node v7, pnpm/action-setup v6, codecov v7, wrangler v4 (7712657, #475)

Dependency, tooling, and test-harness maintenance release; no changes to the public API.
