Per-role Playwright runs no longer call `npm install` against
registry.npmjs.org on every invocation. A new `01_setup.yml` runs once
per host/version, populates `_shared/node_modules/` inside the Playwright
container, and stamps the installed version in `.installed-version`.
Each `02_run_one.yml` mounts that tree read-only at `/e2e/node_modules`
and the container command becomes `npx --no-install playwright test`.
This eliminates the npmjs.org TLS-handshake flake that took out the
keycloak playwright in a recent variant-2 update, saves ~4 s per role,
and gives version bumps a single rebuild point.
Three retry layers cover transient registry failures: Ansible (3× with
5 s delay), npm fetch (5× with 10-60 s backoff), and image pull (3×).
Stage-base / shared-dir / stamp / node_modules paths live as SPOT
constants in `vars/main.yml` so call sites never reconstruct them.
Renames `tasks/run_one.yml` → `tasks/02_run_one.yml` (and adds
`01_setup.yml`) to make the include order visible by filename; updates
cross-references in `AGENTS.md`, the two `docs/contributing/...` pages,
`dump_disk_diagnostics.sh`, and the lint test.

Drops `MAX_LINES` from 12 to 11 in `test_inline_script_block_size.py`,
catching the five blocks that were sitting exactly on the previous
threshold. Pure-bash blocks move to dedicated `.sh` files invoked via
`ansible.builtin.script:` or `run: bash …`; the keycloak heredoc with a
templated JSON payload splits into a `set_fact` plus a folded
`printf | kcadm … -f -` one-liner.
