Base v1.1.0

Changed

• Suppressed pip self-upgrade notices during Base-managed pip installs so
  setup output stays focused on Base actions and real install failures.
• Made live workflow docs and installer examples main-ready, using default-branch
  URLs for raw GitHub install scripts and main for contributor branch
  examples.
• Documented the boundary for optional personal shell defaults such as color
  aliases, navigation shortcuts, signing helpers, and strict shell modes.
• Improved opt-in Bash and Zsh completion ergonomics for interactive shell
  defaults.
• Added conservative pager and terminal usability behavior to opt-in shell
  defaults.
• Enriched opt-in shell history defaults for basectl update-profile --defaults.
• Made Homebrew-managed version: latest profile and project artifacts report
  outdated installed packages during check/doctor and upgrade them during
  setup.
• Renamed the Base-managed GitHub Project metadata schema from base-roadmap
  to base-project.
• Made basectl repo configure report missing BASE_PROJECT_TOKEN Project
  intake secrets and improved generated workflow diagnostics when the Actions
  token cannot see repo Projects.
• Made Homebrew-managed basectl update preflight tap trust before upgrading
  Base when Homebrew requires trust for the tap-owned base-bash-libs
  dependency.
• Removed Base's bundled reusable Bash std, file, and git libraries;
  Base now requires external base-bash-libs through an explicit override,
  sibling checkout, or Homebrew package.

Fixed

• Made Homebrew artifact dry-run tests independent of the developer machine's
  installed or outdated Homebrew formulae.
