Base v1.2.0

Added

• Added basectl workspace init to clone a workspace repository, read its
  workspace configuration, and clone the repositories declared by that
  workspace.
• Added basectl prompt list and basectl prompt product-self-review to render
  repo-owned Markdown prompts for periodic AI-assisted Base workflow reviews.
• Added a local command-history index for Python-backed Base command runs.
• Added manifest-declared PR policy support for Base-managed GitHub PR helpers.
• Added project Python version requirements and declarative artifact registry
  support for Base-managed artifacts.

Changed

• Added ctx.workspace_root to base_cli.Context so workspace-aware commands
  can use the configured workspace root without reaching through user config.
• Improved basectl repo clone, repo check, repo configure, and
  gh issue create|start diagnostics so repository workflow failures include
  clearer update, chmod, origin, Project-field, and worktree-command guidance.
• Made basectl repo configure warn when Homebrew reports the local GitHub CLI
  package is outdated, pointing users to basectl setup --profile dev.
• Made lifecycle command usage errors compact and consistent, returning exit
  code 2 for setup, check, doctor, onboard, and update-profile.
• Made idempotent basectl setup reconciliation quieter when no action is
  required.
• Added base_cli.testing.invoke(..., manifest={...}) for project-aware tests
  that need a fixture base_manifest.yaml.
• Added optional stream and formatter overrides to base_cli.configure_logger
  for tests and CI wrappers that need to capture or reshape user-facing logs.
• Added base_cli.App(help=...) support for subcommand group help text.
• Added standard --quiet / -q support to base_cli.App to suppress INFO
  output on the user-facing stream while preserving warnings, errors, and
  persistent DEBUG log detail.
• Documented the base-bash-libs Homebrew/core readiness path, including the
  formula-name audit command and future basefoundry dependency plan.
• Documented the basectl setup parallelism evaluation and the decision to
  keep mutating setup serial until a setup-plan/preflight layer exists.
• Corrected 1.1.0 documentation status, source-checkout base-bash-libs
  prerequisites, future-design banners, and CI bootstrap package guidance.

Fixed

• Fixed basectl prompt -v <name> so the verbose flag no longer counts as a
  second prompt argument.
• Added actionable recovery guidance when basectl update-profile detects a
  runtime BASE_HOME mismatch.
• Fixed workspace reports for uv-managed project virtual environments and
  broken project virtualenv detection.
• Fixed project --recreate-venv repair and fail-fast runtime directory
  handling for check diagnostics.
• Allowed standard base_cli.App options such as --debug and
  --environment before subcommand names.
• Made base_cli.option(..., dry_run=True) reject duplicate dry-run markers on
  the same command function.
• Made default base_cli.App(max_log_files=...) log retention prune by
  timestamp-prefixed run-id filename instead of filesystem modification time.
