The opt-in code/supply-chain scanners (semgrep, gitleaks, trufflehog, trivy,
syft, grype, checkov) are subcommand-driven and non-networked, but had no
bespoke arg template — so adapterToCustomTool fell through to DEFAULT_TEMPLATE
and spawned `<binary> <target>`. For these that is a broken invocation:
`semgrep <host>` never runs a scan, and with no target it is `semgrep ''`.
semgrep in particular is advertised on the arsenal's headline tool list.
Add per-binary templates that mirror each tool's catalog commandHint and
operate on a filesystem PATH (default: the working dir "."):
semgrep → scan --config auto --json <path>
gitleaks → detect --source <path> --report-format json --redact --no-banner
trufflehog → filesystem <path> --json --no-update
trivy → fs --format json <path>
syft → dir:<path> -o cyclonedx-json
grype → dir:<path> -o json
checkov → -d <path> -o json
Subcommand + output flags are hardcoded (never taken from an LLM string),
matching the conservative pattern of the existing templates. The path is the
only tunable and is sanitised by scanPath(): a leading '-' (flag injection) or
an inherited http(s) mission target is rejected in favour of ".". Option-looking
targets are still refused up front by the factory's existing guard (no spawn).
Adds table-driven tests asserting the exact argv for each scanner, the "."
default, http(s)-target rejection, and the option-looking-path refusal.
