fix(cli): promote --format to global CLI callback option per spec
Add `fmt: OutputFormat` parameter to `main_callback()` in
`src/cleveragents/cli/main.py` and store the selected format in
`ctx.obj["format"]` so all subcommands can read it without needing
their own per-command `--format` flag.

Remove per-command `--format` / `fmt` parameters from `version()`,
`info()`, and `diagnostics()` commands. These commands now read the
format from `ctx.obj.get("format", OutputFormat.RICH.value)`.

The specification states: "The framework supports six distinct output
formats, selectable via the global `--format` flag." This change
aligns the implementation with the spec by making `--format` a global
option on the root `agents` command (via the Typer callback).

All six formats (json, yaml, plain, rich, table, color) are supported
via the global flag and the `-f` shorthand.

Add Behave BDD scenarios covering global `--format` flag propagation
to subcommands for all six formats. Update Robot Framework integration
tests to exercise the global `--format` flag. Update existing tests
that used per-command `--format` for version/info/diagnostics to use
the global flag instead.

Feature: CLI consistency and UX polish
As a developer
I want all CLI commands to follow consistent UX patterns
So that the tool is predictable and easy to use
# -----------------------------------------------------------------
# Exit code constants
# -----------------------------------------------------------------
Scenario: Exit code constants are defined
Given the CLI constants module is imported
Then EXIT_SUCCESS should equal 0
And EXIT_ERROR should equal 1
And EXIT_USAGE should equal 2
And EXIT_NOT_FOUND should equal 3
And EXIT_CONFLICT should equal 4
# -----------------------------------------------------------------
# Error formatting
# -----------------------------------------------------------------
Scenario: cli_error displays standardized error and exits
Given the CLI errors module is imported
When I call cli_error with only message "something broke"
Then the process should exit with code 1
And the stderr output should contain "Error:"
And the stderr output should contain "something broke"
Scenario: cli_error displays hint when provided
Given the CLI errors module is imported
When I call cli_error with message "not found" and hint "check the name"
Then the process should exit with code 1
And the stderr output should contain "Hint: check the name"
Scenario: cli_error uses custom exit code
Given the CLI errors module is imported
When I call cli_error with message "bad usage" and exit code 2
Then the process should exit with code 2
Scenario: cli_warning displays warning without exiting
Given the CLI errors module is imported
When I call cli_warning with only message "heads up"
Then the stderr output should contain "Warning:"
And the stderr output should contain "heads up"
Scenario: cli_warning displays hint when provided
Given the CLI errors module is imported
When I call cli_warning with message "slow" and hint "use cache"
Then the stderr output should contain "Hint: use cache"
Scenario: cli_not_found formats correctly and exits with code 3
Given the CLI errors module is imported
When I call cli_not_found with type "Project" and name "missing-proj"
Then the process should exit with code 3
And the stderr output should contain "Project 'missing-proj' not found"
And the stderr output should contain "Hint:"
# -----------------------------------------------------------------
# Format constants
# -----------------------------------------------------------------
Scenario: Format constants are consistent
Given the CLI constants module is imported
Then FORMAT_HELP should mention "json"
And FORMAT_HELP should mention "yaml"
And FORMAT_HELP should mention "plain"
And DEFAULT_FORMAT should equal "rich"
And VALID_FORMATS should contain "json"
And VALID_FORMATS should contain "yaml"
And VALID_FORMATS should contain "plain"
And VALID_FORMATS should contain "table"
And VALID_FORMATS should contain "rich"
Scenario: Named format shortcut constants are defined
Given the CLI constants module is imported
Then FORMAT_TEXT should equal "plain"
And FORMAT_JSON should equal "json"
And FORMAT_TABLE should equal "table"
# -----------------------------------------------------------------
# Help text consistency
# -----------------------------------------------------------------
Scenario: Main CLI provides help output
Given a CLI consistency test runner
When I invoke the CLI with "--help"
Then the invoked CLI exit code should be 0
And the invoked CLI output should contain "AI-powered development assistant"
Scenario: Version command provides output
Given a CLI consistency test runner
When I invoke the CLI with "--version"
Then the invoked CLI exit code should be 0
And the invoked CLI output should contain "CleverAgents"
Scenario: Invalid command returns usage exit code
Given a CLI consistency test runner
When I invoke the CLI with "nonexistent-command-xyz"
Then the invoked CLI exit code should be 2
# -----------------------------------------------------------------
# Shell completion command
# -----------------------------------------------------------------
Scenario: Completion command exists
Given a CLI consistency test runner
When I invoke the CLI with "completion --help"
Then the invoked CLI exit code should be 0
And the invoked CLI output should contain "completion"
Scenario: Completion rejects unsupported shell
Given a CLI consistency test runner
When I invoke the CLI with "completion ksh"
Then the invoked CLI exit code should be 2
# -----------------------------------------------------------------
# JSON/text format switching
# -----------------------------------------------------------------
Scenario: Version command supports JSON format via global --format flag
Given a CLI consistency test runner
When I invoke the CLI with "--format json version"
Then the invoked CLI exit code should be 0
And the invoked CLI output should be valid JSON
Scenario: Version command supports YAML format via global --format flag
Given a CLI consistency test runner
When I invoke the CLI with "--format yaml version"
Then the invoked CLI exit code should be 0
And the invoked CLI output should contain "version:"
Scenario: Version command supports plain format via global --format flag
Given a CLI consistency test runner
When I invoke the CLI with "--format plain version"
Then the invoked CLI exit code should be 0
And the invoked CLI output should contain "version:"
