chore(deps): exclude GHSA-w4pp-8pjf-rmxw pacote DoS advisory

pacote's addGitSha() has a DoS via malicious spec.rawSpec (CVE-2026-9496,
CVSS 7.7). pacote is only pulled in transitively via dev/build tooling
(lerna pinned to pacote@21.0.1, @npmcli/arborist, yeoman-generator) and
never processes untrusted input - specs come only from our own
package.json/yarn.lock. No fixed pacote version is compatible with
lerna's current pin, so exclude per existing pattern in osv-scanner.toml.
