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.

+## 2. Client Changes
+
+- [x] 2.1 Update `GetBoard` in `client/boards.go` to parse `labels`, `cardLabels`, and `cardMemberships` from `included` response
+- [x] 2.2 Update `ListCardsByBoard` in `client/cards.go` to build label-name map from board's `CardLabels` and `Labels`, and populate `Labels` on each `CardWithList`
+
+## 3. Verification
+
+- [x] 3.1 Build and test `pcli board get <id>` — verify JSON output includes labels and cardLabels when present
+- [x] 3.2 Test `pcli card list --board <id>` — verify each card includes a `labels` array
+- [x] 3.3 Test card with no labels returns empty array (not null)
