v2026.09.0

The command is now pb, not proj. brew install proj installs PROJ, the
cartographic projections library, which puts a proj binary on PATH and
arrives as a dependency of gdal, postgis and qgis. Shipping a tool that shadows
it, or gets shadowed by it depending on PATH order, was a defect rather than a
preference. Nothing in Homebrew or on a stock macOS installs a pb command.

• proj.py is now pb.py, the shell function is pb, and the environment
  variable the function sets is PB_SHELL_WRAPPER
• The data directory moved from ~/.proj to ~/.pb. It migrates itself on
  first run, and only when the old directory exists and the new one does not, so
  it can never merge two sets of data or overwrite anything. The notice goes to
  stderr so that stdout stays parseable
• Re-run bash install.sh && source ~/.zshrc to replace the old shell function.
  The old proj name is deliberately not kept as an alias: it would re-create
  the collision for exactly the people the rename protects
• Add pb list --json for scripts and agents. It emits the same object shape as
  pb info --json, which means the stored fields plus status, computed from
  last_worked_at rather than stored. Filters, sorting and --limit apply, so
  the JSON is exactly what the table would have shown; an empty result is []
  rather than prose
• Ship a Claude Code skill at skills/pb/SKILL.md so an agent can resolve a
  project the user names out loud into a path. install.sh offers to link it
  into ~/.claude/skills/ and defaults to no, because a project CLI has no
  business writing into an agent's config directory uninvited
• Remove every em dash and en dash from the repository, including the ADR
  templates that get scaffolded into other people's projects, and add a test
  that fails if one comes back
• pb info now prints - rather than an em dash for an empty field
