feat(cli): implement context list and context add CLI commands for ACMS

Implements the actual CLI code for context list and context add commands:
- Added --tag, --policy, --format parameters to context add command
- Added --format parameter to context list command (table|json output)
- Rewrote BDD step definitions to use Typer CliRunner for real CLI invocation
- Fixed AmbiguousStep conflicts across step files
- Removed IMPLEMENTATION_NOTES.md developer scratchpad
- Added CHANGELOG.md entry under [Unreleased] > Added

 ## [Unreleased]
 
+### Added
+
+- **ACMS `context list` and `context add` CLI commands** (#9585): Implemented
+  `agents actor context list` to display all indexed context entries with tier,
+  size, and last-accessed metadata (supports `--format table|json`). Implemented
+  `agents actor context add <path>` with `--tag`, `--policy`, and `--format`
+  flags for indexing files and directories into the ACMS. Added comprehensive
+  BDD test coverage with 27 scenarios using Typer `CliRunner` for real CLI
+  invocation.
+
 ### Fixed

-## Feature: ACMS context list and context add CLI commands
-
-### Status
-- Feature file created: `features/acms_context_list_add_cli.feature`
-- Step definitions created: `features/steps/acms_context_list_add_cli_steps.py`
-- CLI commands already exist in `src/cleveragents/cli/commands/context.py`
-
-### What's Implemented
-
-#### 1. Feature File (`acms_context_list_add_cli.feature`)
-Comprehensive BDD test scenarios covering:
-- `context list` command with table and JSON output formats
-- `context add` command with file/directory support
-- Support for `--tag` and `--policy` flags
-- Support for `--format` flag (table/json)
-- Display of tier, size, and last-accessed metadata
-- Help documentation for both commands
-- Integration scenarios combining list and add operations
-
-#### 2. Step Definitions (`acms_context_list_add_cli_steps.py`)
-Complete step implementations for:
-- Creating temporary projects and files
-- Running context list/add commands
-- Verifying output formats (table and JSON)
-- Checking metadata (tier, size, last-accessed)
-- Validating command success/failure
-- Testing tag and policy flags
-
-### What Needs Enhancement
-
-The existing CLI commands in `context.py` need the following enhancements:
-
-#### 1. `context_add` Function
-Add parameters:
-- `tag: str | None` - Optional tag for context entry
-- `policy: str | None` - Optional policy (hot/warm/cold) for tier management
-- `format_type: str` - Output format (table/json)
-
-Update the `add_to_context` service call to pass these parameters.
-
-#### 2. `context_list` Function
-Add parameter:
-- `format_type: str` - Output format (table/json)
-
-Add JSON output support alongside existing table format.
-
-#### 3. Context Service (`context_service.py`)
-Enhance `add_to_context` method to:
-- Accept optional `tag` and `policy` parameters
-- Store these metadata with context entries
-- Support ACMS tier management
-
-### Testing Strategy
-
-The feature file includes 30+ scenarios covering:
-1. **List Command Tests** (11 scenarios)
-   - Empty context
-   - Table output with metadata
-   - JSON output format
-   - Tier information display
-   - File size formatting
-   - Last-accessed metadata
-   - Help documentation
-
-2. **Add Command Tests** (13 scenarios)
-   - Single file addition
-   - Directory addition (recursive and non-recursive)
-   - Tag and policy flags
-   - Multiple file addition
-   - Error handling (non-existent files)
-   - JSON output format
-   - Help documentation
-
-3. **Integration Tests** (3 scenarios)
-   - Add then list workflow
-   - Multiple files with different policies
-   - JSON format with complete metadata
-
-### Coverage Goals
-
-Target coverage >= 97% for:
-- `context_add` function
-- `context_list` function
-- JSON/table output formatting
-- Tag and policy handling
-- Error cases
-
-### Next Steps
-
-1. Update `context_add` function signature to include `tag`, `policy`, and `format_type` parameters
-2. Update `context_list` function signature to include `format_type` parameter
-3. Enhance `add_to_context` service method to handle tag and policy
-4. Implement JSON output formatting for both commands
-5. Run full test suite to verify all scenarios pass
-6. Ensure coverage >= 97%
-
