Node 24.18.0 lands with crypto and perf fixes

Node.js 24.18.0 LTS release ships (9f23e70)

Node 24.18.0 "Krypton" is out, bundling several user-facing changes: Buffer's default pool size is increased to 64 KiB, crypto docs and behavior are tightened, and root certificates are refreshed. The release also carries API/doc updates across core modules, so this is a meaningful maintenance drop for the LTS line.

Reject small-order EdDSA points during verification (2989072)

Ed25519 and Ed448 one-shot verification now returns false when the public key or signature R component is a known low-order point. This closes a cryptographic correctness gap and aligns WebCrypto verification behavior with WPT expectations across OpenSSL variants.

Fix Readable.wrap() proxying for the first own method (07e27ad)

Readable.prototype.wrap() now starts proxying own enumerable keys at index 0 instead of 1, so the first method on a wrapped legacy stream is no longer silently skipped. This fixes a subtle interop bug that could leave wrapped methods unavailable depending on property order.

Expose the GC minor mark-sweep perf_hooks constant (5075bb4)

Node now exports perf_hooks.constants.NODE_PERFORMANCE_GC_MINOR_MARK_SWEEP, matching V8's kGCTypeMinorMarkSweep when --minor-ms is enabled. That gives consumers a stable constant for interpreting GC performance entries instead of seeing an unmapped numeric kind.

Improve REPL startup and completion performance (745a43e)

The REPL now lazy-loads acorn, acorn-walk, and the global builtins set instead of paying those costs on builtin load. That trims startup overhead and defers the expensive work until parsing, completion, or recoverable-error checks actually need it.

Tighten test-runner and inspect diagnostics (266e165, ff58f43)

Test-runner coverage failures now include the coverage filename and child-process output, making missing-report failures much easier to debug. Separately, util.inspect() no longer risks an out-of-memory loop when formatting stack traces that end at a node_modules path component.
