Follow-up to #2127. The extra Nemotron start-up line there is main's noteParked: it logs at info level whenever 0.25 GiB or more happens to sit on the kernel's per-CPU page lists at start-up. So the line shows up or not depending on the box's memory state (in the rerun table, #2127 (comment), main read 0.45 to 0.53 GiB, and the first run had read below 0.25).

This moves the line to debug level. The budget still counts the parked pages, as #1323 intended; only the log level changes. Both callers (cuda.zig, the CUDA budget and the rank room) are unchanged.

zig build test and the no-GPU CI steps (kernel contract, golden, server and pull security, fuzz) pass. Lean adds 0 problems against main.

Thanks @jschmied, moving noteParked to debug is the right fix for #2127's start-up line, and the budget keeps counting the pages. One thing: the CHANGELOG hunk edits #1651's entry under 1.2.2, a released section, with a note about the larger chunk's memory. That's worth saying, but not in this PR. Could you drop that hunk here and, if you'd like, send the 4.6 GiB note as its own docs change under Unreleased? Then this is ready to land.

Thanks @ashhart, and sorry for the delay. The hunk is out: this PR no longer touches CHANGELOG.md, so #1651's entry reads as released. It's now only noteParked at debug and its test.

I'll leave the 4.6 GiB note for now and send it as its own docs change if it still seems worth saying.
