Julius BrusseeandClaude Opus 4.7 754795ada4 fix(install): unbreak curl|bash one-liner (regression in v1.8.0)
Two bugs at the curl|bash entry point made the headline install command
fail immediately:

1. install.sh used `${BASH_SOURCE[0]}` under `set -u`. That variable is
   unset when bash is invoked from stdin (curl | bash), tripping the
   nounset trap before we ever reached the npx fallback.
2. install.sh + install.ps1 passed `--` between npx and the package args.
   On modern npm, npx forwards the literal `--` to bin/install.js, which
   parseArgs rejected as an unknown flag.

Fix:
- install.sh: default BASH_SOURCE[0] to empty so the curl-pipe path falls
  through cleanly under set -u.
- install.sh + install.ps1: drop the `--` separator. npm 7+ npx already
  forwards trailing args correctly.
- bin/install.js parseArgs: accept a bare `--` as a no-op (POSIX
  end-of-options marker) so future shim drift can't re-break this.
- New regression test asserts `--` is accepted.

# caveman — installer shim (Windows / PowerShell).
#
# Thin wrapper around bin/install.js (the unified Node installer). Every flag
# you'd pass to bin/install.js can be passed here; we just forward them.
#
# One-line install:
# irm https://raw.githubusercontent.com/JuliusBrussee/caveman/main/install.ps1 | iex
#
# Local clone:
# pwsh install.ps1 [flags]
#
# Why a Node installer? install.sh + install.ps1 used to be parallel sources of
# truth and constantly drifted (issue #249 was a `node -e "..."` quoting bug
# that silently dropped the JSON merge step on every Windows install). One
# Node script works everywhere without quoting bugs.
