- Around line 5-7: Update the action metadata so the description matches the
actual default and make the TODO actionable: change the description value to
state that the default node version is '22.x' (instead of claiming 'lts'), and
revise the inline TODO comment to note that Node 20 reaches EOL on 2026-04-30
and that the plan is to revert the default to 'lts/*' after that date; make sure
to keep the default: '22.x' entry intact and clearly document the temporary
nature of this override.

- Line 74: Update the Node version statement in cli/README.md to match the CI
and root package.json engine requirement: change the current "Node.js v20 LTS or
higher" wording to "Node.js v22+ (>=22.11.0)" or equivalent phrasing that
reflects the exact engine floor from the root package.json's engines field;
ensure the README text and any contributor setup notes consistently reference
Node 22+ so they align with the CI workflow change (node-version: ["22.x",
"24.x"]) and the package.json engines entry.
