215 curated tools across 21 categories, an AI guidance layer (intent to tools,
tool+goal to command, findings summary, report drafting), the /goal step-by-step
objective planner, and /find GitHub tool discovery.

Breaking changes — the rework removes user-facing paths the old README
documented:
  - install.sh, install.py, requirements.txt and update.sh are gone; installs are
    now standard and verifiable (pipx from a checkout, Docker, or a release
    artifact).
  - The in-app self-update that shelled out to git pull / install.py / /usr/share
    is replaced by honest per-channel guidance.
  - The flat top-level layout moved to src/hackingtool/ behind the 'hackingtool'
    console entry point, so 'python hackingtool.py' no longer applies.

Re-install using one of the paths in the README before upgrading.
