Without a repo config, the Prettier CLI and Trunk used the default
width of 80, while editors with a user printWidth reflowed files on
save, producing formatting-only diffs. Pin the width in .prettierrc.json
and reformat source, tests, scripts and JS/TS config files to match.
Files that already failed Prettier at width 80 for unrelated reasons
(tsconfig*.json, .trunk/*, V2_FAQ.MD) are left untouched.
No code changes.

Add an .actrc, runner Dockerfile, push event payload, and
scripts/dev/act_ci.sh to run ci.yml jobs locally with nektos/act.
The script refuses --bind/--reuse in .actrc, since a bound checkout
runs as root and rewrites ownership and modes in the working tree.
Document the @latest-v2 version label in the README.
