chore: pin memtrack 1.5.0

[adriencaccia]

Point the runner at memtrack 1.5.0, which ships physical (resident) memory
tracking. The feature stays off unless
--experimental-memory-track-physical (or
CODSPEED_MEMTRACK_TRACK_PHYSICAL=1) is passed.

Refs COD-3499 — the issue stays open until the runner release that carries
this pin.

Greptile Summary

Updates the pinned memtrack installer from version 1.4.0 to 1.5.0 and replaces its SHA-256 digest, enabling the runner to use the release that supports opt-in physical memory tracking.

Confidence Score: 5/5

The PR appears safe to merge with no actionable compatibility or integrity issue identified.

The version and checksum update follows the existing binary-pin mechanism, is covered by network-backed checksum validation in CI, and preserves the runner’s memtrack installation and runtime contracts.

Important Files Changed

Filename	Overview
src/binary_pins.rs	Updates the memtrack installer version and corresponding integrity digest; existing CI validates the published asset against the pin.
