Collapse the multi-line rationale blocks that accreted across the torch
index, override, redaction and companion-pin work to single-line
constraints, and drop review-history narration. Comments and blank lines
only; the PowerShell files verify code-identical by token-stream
comparison against the previous commit, install.sh passes sh -n, and the
Python file passes the AST comments-only gate.
install.sh -258 lines, install.ps1 -235, studio/setup.ps1 -304,
studio/install_python_stack.py -182. One test touched:
tests/sh/test_mac_intel_compat.sh anchors its awk extraction on a
comment phrase that was shortened; the anchor now matches both wordings.
Full battery: parity/install-stack/pr5940 pytest suites, all sh suites
(host-defaults is the known pre-existing failure), and the four studio
ps1 suites all pass.
