chore(release): prepare 2.0.2

[DavidBabinec]

Prepares the 2.0.2 release. Bumps the version across the ten pinned files via bun run bump and closes the changelog by dating the [Unreleased] heading as 2.0.2 - 2026-08-28. No behavior change.

2.0.2 collects five fixes already on main: the Figma save (localStorage), the Figma plain-permalink connection, the Oxygen Classic font escaping, disabled fonts in the Oxygen and Bricks builders, and local fonts whose family name contains a space.

Verification

bun run test:www          # 156 pass, 0 fail
bun run build:wp          # clean
bun run build:figma       # clean
bun run check:open-source # clean
cd packages/wp && bun run php-test  # 36 pass

Notes

Tag and publish are not part of this PR. After merge, cutting v2.0.2 (bun run release) is a separate, explicit step.
