fix(sentry-cli): re-path source to packages/cli/plugins/sentry-cli + bump ae9a84c5 → 94a4ca58 (#4825)

Upstream getsentry/cli restructured to a pnpm-workspace monorepo
(getsentry/cli@96390e5, 2026-07-31); the pinned subdir plugins/sentry-cli
no longer exists at HEAD. The plugin moved intact to
packages/cli/plugins/sentry-cli (Sentry's own .claude-plugin/marketplace.json
declares it there; plugin version 0.40.0 -> 0.41.0). Validated at the new
path+SHA with claude plugin validate.
