chore: adopt astro-pigment 0.20.1, upgrade docs app to Astro 7

astro-pigment 0.20.x raises its astro peer to ^7.0.0, forcing the Astro 7
upgrade plus matching @astrojs/check and ts-plugin bumps.

Exclude astro-pigment (first-party) and es-toolkit from the release-age
cooldown; both blocked the install.
