fix(cli): stop cli startup hanging on macos (CLI-2485)

[7ttp]

TL;DR

stops every cli command on macos from waiting on the automounter before it prints anything.

whats broken?

since #6506 every command loads the stack code at startup,
and msgpackr inside it probes for its native addon at the linux build runner's store path baked into the binary

on macos that /home/runner path goes through the automounter on every run, and when the lookup stalls every invocation blocks in open(2)

now fixed by:

setting msgpackr's own MSGPACKR_NATIVE_ACCELERATION_DISABLED
switch at build time for the release and build:binary binaries. the addon never ships in the binary, so msgpackr keeps its js path like it already did wherever that path is missing, and it no longer loads an addon from that path when one exists..

ref:

• closes: 2.118.0-beta.72 (darwin-arm64): supabase --version blocks forever in open(2), and one stuck process blocks every later invocation #6771
• broken in: feat(cli): add experimental stack start #6506
