Add Audit.ScanHomebrew, which shells out to "brew vulns --json" (the
homebrew/brew-vulns tap) to cover the Homebrew formulae that ScanOSV
skips. It resolves each formula's source repo and version tag and
queries OSV via the GIT ecosystem.
brew-vulns exits 1 when vulnerabilities are found, so success is
detected by parseable JSON on stdout rather than the exit code; if the
tool is not installed the scan is skipped with a notice instead of
failing the audit. Qualitative severities are mapped through the
existing severityLabelToScore/cvssToSeverity helpers for consistency.

Fix bash 3.2 parser error on escaped space in collect-inventory.sh
(=~ ^require\ ]] -> [[:space:]]). Remove unused Go imports in
cmd/audit/main.go and internal/security/claude.go, and an unused
test variable in osv_test.go so go build and go vet pass.
