fix(cli): fix project context show test mock for tier service

Add ContextTierService mock to step_m5_invoke_project_context_show
so the CLI command can call _get_context_tier_service() without
failing. Also patch _load_policy_json to prevent JSON decode errors
from MagicMock session objects. Update CHANGELOG.md and CONTRIBUTORS.md.

+### Fixed
+
+- **`agents project context show` JSON/YAML output** (#6323): Fixed structured output to include spec-required envelope (`command`, `status`, `exit_code`, `data`, `timing`, `messages`) and all four data sections (`context_policy`, `limits`, `summarization`, `current_usage`). Rich output now renders four panels including the new `Current Usage` panel.
+
 ### Added
 
 - **A2A module rename BDD test suite** (#8615): Comprehensive Behave tests validating that the ACP→A2A module rename is complete — verifying all 22 A2A symbols are properly exported, no legacy ACP references remain in `.py` files under `cleveragents.a2a/`, and the module docstring uses current A2A naming. The step definitions include self-contained symbol lookups to avoid cross-scenario dependency failures.
