Bump inter-package peerDeps to ^0.8.0 + fix release.yml sync bug

Two bugs in one fix:

1. The 0.8.0 release commit only bumped .version, not the inter-package
   peerDependencies / devDependencies. So the published packages still
   declared peer constraints like "@pascal-app/viewer": "^0.7.0". Caret
   in semver 0.x doesn't allow 0.8.0 to satisfy ^0.7.0, so bun resolves
   workspace consumers (and apps/editor's deep import paths) to the
   stale npm-published 0.7.0 instead of the workspace 0.8.0 — meaning
   local edits never show up in apps/editor or any linked consumer.

2. The release.yml sync step was using $GITHUB_ENV to read back the new
   versions in the same step, which doesn't work — env-file writes only
   surface in subsequent steps. Switched to a bash associative array
   (NEW_VERSIONS) for in-step lookup, kept the $GITHUB_ENV write for the
   downstream publish/commit/tag steps. Also added a final "refs after
   sync" debug print so this is visible in the workflow log.

After this lands and you bun install, packages/editor/node_modules/@pascal-app/viewer
should symlink to the workspace packages/viewer/, not to .bun/@pascal-app+viewer@0.7.0.
Future releases will sync peerDeps correctly on their own.
