feat: Add openspec-sync-specs and openspec-verify-change skills

- Introduced `openspec-sync-specs` skill to sync delta specs to main specs, allowing intelligent merging of requirements.
- Added `openspec-verify-change` skill to verify implementation against change artifacts, ensuring completeness, correctness, and coherence before archiving.

docs: Create CLAUDE.md for project guidance

- Added CLAUDE.md to provide an overview of the PCLI project, including build, test commands, architecture, and resource addition guidelines.

chore: Add new change and design documents for project filter in status command

- Created `.openspec.yaml`, `design.md`, `proposal.md`, and `tasks.md` for the `add-project-filter-to-status` change.
- Updated specs for CLI commands and status command to include project filtering functionality.

feat: Expand board included parsing in API client

- Added parsing for `labels`, `cardLabels`, and `cardMemberships` in the `GetBoard` response.
- Updated `ListCardsByBoard` to enrich card output with label names, enhancing usability in kanban sync workflows.
