Fix/seed banner alignment 302

[Vignesh-P-C]

Description

scripts/seed_demo_subjects.py printed a hand-drawn Unicode box banner with manually space-padded lines. One line (STATEWAVE_BOOTSTRAP_DEMO_PACKS=false) was longer than the fixed border width, so its closing │ didn't align with the rest of the box in a monospace terminal. This PR replaces the manual banner with a _print_seed_banner() helper that auto-sizes the box to the longest line and pads every line to match, so the borders always align regardless of future wording changes.

Changes Made

• Added _print_seed_banner() helper function that computes box width from the longest line and pads every line to match

Additional Notes

No test suite exists for this script (it's a standalone data-seeding utility, not covered by tests/), so verification was manual: ruff check passed, and running with --dry-run confirms all box borders now align correctly, including the previously-overflowing line.

Thanks — nice fix. Auto-sizing the box to the longest line is the right call; I ran the helper against the real banner text and every border lines up exactly, including the STATEWAVE_BOOTSTRAP_DEMO_PACKS=false line that overflowed before.

One housekeeping thing, done rather than asked: I rebased your branch onto current main (maintainer edits enabled, so I hope that's okay). Your branch still carried the earlier wait_readyz.sh commit from #326 — which has since been merged with slightly reworded comment text — so merging as-is would have clashed with (and partly rolled back) what's on main now. After the rebase this PR is exactly your banner fix, nothing else, and the conflict is gone.

Merging once CI is green. Thanks for closing out #302!
