fix(cli): add spec-required --data-dir, --config-path, and -v global options to main_callback

Implements ADR-021 §Global CLI Flags and ADR-024 §Resolution Chain.
All three global options were missing from main_callback(), causing any
invocation with these flags to crash with 'No such option'.

Changes:
- src/cleveragents/cli/main.py
  * Add _VERBOSITY_LOG_LEVELS tuple mapping verbose count to log levels
    (0=CRITICAL/silent, 1=ERROR, 2=WARNING, 3=INFO, 4=DEBUG, 5+=DEBUG)
  * Add --data-dir PATH option: validates path is a directory if it exists,
    sets CLEVERAGENTS_DATA_DIR env var, resets Settings singleton
  * Add --config-path PATH option: validates file exists and is a file,
    sets CLEVERAGENTS_CONFIG_PATH env var for ConfigService to pick up
  * Add -v (count=True) option: wires verbose count to configure_structlog
  * Store all three values in ctx.obj for subcommand access
  * Update _print_basic_help() to include the three new global options so
    'cleveragents --help' (fast path) also lists them
  * In the catch-all Exception handler, print the original exception
    type+message directly to err_console so actionable details remain
    visible even when log level is CRITICAL (e.g. 'No such option')

- src/cleveragents/application/services/config_service.py
  * ConfigService.__init__ now checks CLEVERAGENTS_CONFIG_PATH env var
    when no explicit config_path is passed, completing the resolution
    chain for --config-path CLI override

Tests (all passing):

- robot/cli_global_options.robot (8 Robot Framework integration tests)

 - **Plan Rollback Command** (#8557): Implemented `agents plan rollback <plan-id> [<checkpoint-id>]` for checkpoint-based plan state restoration in Epic #8493. The command restores a plan's sandbox to the state captured at a given checkpoint, discarding all decisions made after that checkpoint. The checkpoint can be specified as an optional positional second argument or via the `--to-checkpoint` named option. Supports `--yes/-y` flag to skip confirmation prompts and `--format/-f` for output format selection (rich/plain/json/yaml). Included with comprehensive BDD test coverage (>= 97%) and spec-aligned output formatting showing rollback summary, changes reverted, impact analysis, and post-rollback state panels.
 
 ### Fixed
+- **Global CLI options ``--data-dir``, ``--config-path``, and ``-v`` now work correctly**
+  (#6785): These spec-required flags were absent from ``main_callback()`` in
+  ``src/cleveragents/cli/main.py``, causing any invocation with these flags to crash
+  with ``NoSuchOption: No such option``. All three options are now implemented per
+  ADR-021 §Global CLI Flags and ADR-024 §Resolution Chain.  ``--data-dir`` sets
+  ``CLEVERAGENTS_DATA_DIR`` before any ``Settings``-reading code runs, ``--config-path``
+  sets ``CLEVERAGENTS_CONFIG_PATH`` for ``ConfigService`` to pick up, and ``-v``
+  (repeatable count) maps to the appropriate ``structlog`` log level.
+
 - **Actor configuration validation incorrectly requires top-level provider field** (#4300): 
    Actor configuration in V3 is now obtained from the nested configuration 
    parameter, according to the specification.
