Node adds fs buffer reads, keepalive tuning

fs: support caller-supplied readFile() buffers (de67c5c)

fs.readFile() and fsPromises.readFile() can now read directly into a caller-provided buffer or a buffer factory, returning a view over the bytes read. This enables fewer allocations and more control over memory use when reading files.

net: expose TCP_KEEPINTVL and TCP_KEEPCNT in setKeepAlive (1efdce3)

socket.setKeepAlive() now accepts interval and count in addition to the existing keepalive delay, letting users tune probe cadence and drop thresholds from Node. That makes the API much more useful for long-lived connections and maps cleanly to TCP_KEEPINTVL and TCP_KEEPCNT.

debugger: add --max-hit option to probe mode (8c4ec8a)

Probe sessions can now stop as soon as a per-probe hit limit is reached, rather than waiting for timeout or process exit. This is a meaningful ergonomics upgrade for inspector-driven tooling and future attach-to-running-process workflows.

src: officially deprecate node::ObjectWrap (fc28d94)

Node now formally deprecates the long-unmaintained node::ObjectWrap interface and steers addon authors toward public interfaces and newer alternatives. This is an API-shaping change for native addon guidance, with docs updated to reflect the preferred patterns.

src: do not track weak BaseObjects as children of Realms (2fb168f)

Heap tracking was adjusted so weak BaseObject instances no longer show up as if they were strongly retained by Realm/Environment nodes. That fixes misleading heap dumps and makes memory-retainer analysis more accurate for leak hunting.

Other misc changes

• Primordials/frozen-intrinsics coverage tweaks, including adding Iterator to primordials.
• Official ABI registry update for Electron 44.
• Dependency bumps and build metadata updates, including npm 11.17.0 and ngtcp2 configuration.
• Test runner cleanup removing an unused shuffle helper and adding deterministic generator coverage.
