DevTime v0.1.1 - pipx demo onboarding

DevTime v0.1.1 - pipx demo onboarding

An onboarding-focused release. It makes the PyPI/pipx install path the primary way to
try DevTime and adds a one-command demo. No changes to concept detection, risk review,
or scanner behavior.

Highlights

• Install from PyPI: the public distribution is devtime-ei
  (pipx install devtime-ei). The name devtime is reserved on PyPI, so devtime-ei
  is the intended public distribution name.
• New: dtc demo init: copies a small static example repo into
  ./devtime-demo-saas, so you can try DevTime right after installing from PyPI
  without cloning this repository.
• New: dtc demo init --force: replaces an existing ./devtime-demo-saas copy.
• Docs: README and QUICKSTART now start from pipx install devtime-ei followed by
  dtc demo init, with the source install kept as an alternative.

Names

• The PyPI distribution is devtime-ei.
• The Python import package remains devtime.
• The CLI command remains dtc.

Try it

pipx install devtime-ei
dtc demo init
cd devtime-demo-saas
dtc init
dtc scan
dtc concepts
dtc explain "Billing Webhooks"

Safety and scope

• dtc demo init only copies static files into the current working directory. It does
  not execute code, install anything, run tests or migrations, or make network calls.
• No changes to concept detection, risk review, or scanner behavior.
• No cloud, no telemetry, no AI, no network behavior added.

Notes

• The bundled demo ships inside the wheel as package data
  (devtime/resources/demo-saas/); the source tree still keeps examples/demo-saas
  for source installs.
• Tests added for the demo command and the copied-demo scan flow (97 passing).
