feat(status): add --project flag for filtering boards by project name

- Implemented the --project flag in the pcli status command to filter boards based on the specified project name.
- Updated the command to resolve project names to IDs using case-insensitive matching.
- Adjusted the totalBoards count in the output to reflect the number of boards matching the project filter.
- Enhanced command help text and README documentation to include usage examples for the new flag.
- Verified functionality through manual testing and ensured default behavior remains unchanged when the flag is omitted.

feat(board): expand GetBoard response to include labels and card associations

- Modified the Board struct to include Labels, CardLabels, and CardMemberships fields.
- Updated the GetBoard method to parse additional fields from the API response.
- Enhanced ListCardsByBoard to include label names for each card based on the enriched board data.
- Ensured backward compatibility by making new fields optional and preserving existing output structure.
