* chore: auto-sync dev with main after release

* fix: add JSDoc comment to IconName type for better IDE support

* fix: use GitHub API to sync dev with main after release

The previous approach failed because dev branch is protected and requires PRs.

* feat: use peter-evans/create-pull-request for elegant branch sync

Most elegant solution for syncing protected branches:
- Industry standard (175k+ repos use it)
- No PAT required, works with GITHUB_TOKEN
- Handles branch protection automatically
- Idempotent (updates existing PR)
- Auto-deletes branch after merge

* fix: remove duplicate sync step (handled in build.yml)

* fix: add pull-requests permission for branch sync

* feat: extract reusable UI components

Extract repeated UI patterns into reusable components:

- Collapsible: Expandable sections with animated chevron
- FeatureItem: Badge list items (numbered/icon variants)
- Modal + ModalHeader + ModalContent: Dialog overlays with ESC key handling
- Dropdown + DropdownHeader + DropdownSearch + DropdownList: Floating menus

Reduced +page.svelte by 92 lines while improving maintainability.
