The pprof file was a merge from pprof taken from a production block producer and a sentry. This profile allows the go compiler to make more informed optimization decisions during compilation. For more info, see: https://go.dev/doc/pgo

LGTM — straightforward addition of the PGO flag to the build target.
Extended reasoning...
Overview
This PR adds Profile-Guided Optimization (PGO) to the make bor build target by including a -pgo=prod.pprof flag and committing a merged production pprof profile. The change touches two files: a one-line modification to the Makefile and the addition of the binary prod.pprof profile.
Security risks
No security concerns. The change only affects compiler optimization behavior via a standard Go feature (-pgo). The pprof file is a CPU profile used by the compiler — it contains no secrets or executable code.
Level of scrutiny
This is a low-risk, mechanical change. PGO is a well-documented Go compiler feature (available since Go 1.21) that uses profiling data to guide optimization decisions. The worst-case outcome is that the profile provides no benefit; it cannot introduce correctness issues. The inline bug comment about the goreleaser config not including the flag is a valid enhancement suggestion but does not affect the correctness of this change.
Other factors
The PR is small and self-contained with clear intent described in the PR description. The nit about .goreleaser.yml missing the PGO flag for official release builds is already raised as an inline comment and is worth the author considering, but it does not block this change.
