Fix #326: filter //external:* labels from impacted-targets output on …

…bzlmod (#334)

Synthetic //external:<apparent_name> targets created by `bazel mod show_repo`
are needed during generate-hashes (so dep changes are detected) but are not
buildable in bzlmod-only mode (Bazel 8.6.0+ with WORKSPACE disabled), causing
downstream `bazel build` of the impacted-targets file to fail with
"no such package 'external'".

Adds --excludeExternalTargets to get-impacted-targets (negatable, auto-defaults
to true when bzlmod is detected), filters those labels at the output stage,
and adds unit + e2e coverage.
