## ADDED Requirements

### Requirement: Status command summary output
The system SHALL provide a top-level `pcli status` command that outputs a summary of all boards, their lists, and card counts. The summary SHALL include the total number of boards. For each board, the summary SHALL include the board name and a breakdown of each list within that board showing the list name, the number of open cards (where `isClosed` is false), and the number of closed cards (where `isClosed` is true). Empty lists SHALL be included in the output with 0 open and 0 closed cards.

#### Scenario: Status with multiple boards and lists
- **WHEN** `pcli status` is executed and there are boards with lists containing cards
- **THEN** the output SHALL include the total board count
- **AND** each board SHALL list all its lists with open and closed card counts

#### Scenario: Status with empty lists
- **WHEN** a board contains a list with no cards
- **THEN** that list SHALL appear in the output with 0 open cards and 0 closed cards

#### Scenario: Status with no boards
- **WHEN** `pcli status` is executed and there are no boards
- **THEN** the output SHALL indicate 0 boards

#### Scenario: Status with closed cards
- **WHEN** a list contains both open and closed cards
- **THEN** the open card count SHALL exclude closed cards
- **AND** the closed card count SHALL be shown separately

### Requirement: Status command JSON output
The system SHALL output the status summary in the standard JSON envelope format (`{"data": ..., "error": null}`) when `--format json` is used or no format flag is provided. The `data` field SHALL contain an object with `totalBoards` (integer) and `boards` (array). Each board object SHALL contain `id` (string), `name` (string), and `lists` (array). Each list object SHALL contain `id` (string), `name` (string), `openCards` (integer), and `closedCards` (integer).

#### Scenario: JSON output structure
- **WHEN** `pcli status` is executed with `--format json` or no format flag
- **THEN** the output SHALL be a JSON envelope with the status summary as the `data` field

#### Scenario: JSON output field types
- **WHEN** the JSON output is parsed
- **THEN** `totalBoards` SHALL be an integer
- **AND** each list's `openCards` and `closedCards` SHALL be integers

### Requirement: Status command table output
The system SHALL output the status summary in a human-readable table format when `--format table` is specified. The table output SHALL begin with a line showing the total number of boards (e.g., `3 boards`). For each board, the output SHALL display a board header line (e.g., `Board: Sprint Planning`) followed by a table with columns `LIST` and `CARDS`. The `CARDS` column SHALL display the open card count, and if there are closed cards, append ` (<n> closed)` (e.g., `12 (2 closed)`). If there are no closed cards, only the open count SHALL be displayed (e.g., `12`).

#### Scenario: Table output with closed cards
- **WHEN** `pcli status --format table` is executed and a list has 12 open and 2 closed cards
- **THEN** the CARDS column for that list SHALL display `12 (2 closed)`

#### Scenario: Table output with no closed cards
- **WHEN** `pcli status --format table` is executed and a list has 5 open and 0 closed cards
- **THEN** the CARDS column for that list SHALL display `5`

#### Scenario: Table output with empty list
- **WHEN** `pcli status --format table` is executed and a list has 0 open and 0 closed cards
- **THEN** the CARDS column for that list SHALL display `0`

#### Scenario: Table output board count line
- **WHEN** `pcli status --format table` is executed
- **THEN** the first line of output SHALL show the total board count (e.g., `3 boards`)
