Subject: [PATCH 1/2] ci: install Claude Code CLI directly instead of using the
 action

The first version used `uses: anthropics/claude-code-action`, but this
repo's Actions policy is allowed_actions: selected with an empty
patterns_allowed list (only GitHub-owned actions permitted), so both
runs so far (on this PR's own merge, and on the next PR merged after
it) died instantly with startup_failure and no jobs at all.

Installs the Claude Code CLI via npm and invokes it directly with
`claude -p`, using only actions/checkout and actions/setup-node
(GitHub-owned, already allowed). Same prompt and --allowedTools as
before, verified against the actual installed CLI's --help output
rather than assumed.

Also confirmed no untrusted field (e.g. PR title, which any fork
contributor controls) is spliced directly into a run: shell block -
everything relevant is routed through env: first, since this workflow
runs with pull_request_target's elevated, secret-bearing permissions.

Subject: [PATCH 2/2] ci: use ubuntu-latest-large for the doc-sync job

Matches the Twilio runner label already in use by ci.yml, e2e-tests.yml,
and release.yml on master, for consistency with the org's runner
migration.
