Consolidate `/local-review` and `/local-review-uncommitted` into a single `/review` command that uses subcommands (`uncommitted` or `branch`) to determine the review scope.
- Replace deprecated `/local-review-*` slash commands with `/review [scope]`
- Update documentation to reflect new command syntax
- Update telemetry to track the unified `review` command
- Update test suites to validate new command parsing and behavior
- Refactor review prompt templates and logic to support the new structure
