Commit 3dfb35700 accidentally saved scripts/install.ps1 with a UTF-8 BOM
(EF BB BF) at byte 0. PowerShell's normal file-execution path (`& .\install.ps1`)
handles BOMs fine, but the curl-and-iex one-liner documented in the README
uses `[scriptblock]::Create((irm ...))` which does NOT strip BOMs — the
BOM lands inside the param() block and fails with 'The assignment
expression is not valid' on $Branch and $HermesHome.
teknium1 hit this trying to reinstall from the PR branch after Brooklyn's
commits landed. Every user trying the PR branch install-one-liner hit
it too until we notice.
Saved without BOM, verified via xxd: file now starts with '# =====' at
byte 0 instead of EF BB BF.
