fix: make site base path configurable + remove unused workflow (#56)

* fix: make site base path configurable + remove unused workflow

- Make astro.config.mjs read site/base from ASTRO_SITE and ASTRO_BASE
  env vars with GitHub Pages defaults. Azure SWA can now build with
  ASTRO_BASE=/ so images resolve correctly at root.
- Remove unused squad-heartbeat.yml workflow.

* fix: normalize base path and prevent // in nav links

Address review feedback: normalize ASTRO_BASE to prevent double-slash
URLs when base is '/'. Also fix Header.astro to strip trailing slash
from BASE_URL before concatenating nav link paths.
