feat(bootstrap): --demo mode for try-it-out evaluation (M-4) - #29

Conversation
scripts/init-project.sh --demo synthesizes a throwaway Node.js source repo (templates/demo-source: 3-file scratch with one git commit) in a temp dir, then delegates to the existing --non-interactive path with an auto-generated config wiring a single backend role at it. Zero prompts, fully-configured sprint-config.yaml + filled be-engineer.md + initialized KB + workflow symlinks. Ready for `/sprint demo-1` in Claude Code. Closes the "can't evaluate zachflow without first having a target codebase" friction from the install/setup review. --demo is mutually exclusive with --from=<file>. The closing banner names the throwaway path so the user can rm -rf it when finished. New tests/demo-mode-test.sh covers happy path, source-repo materialization (.git + 1 commit + role.source wired correctly), cleanup-banner content, and the flag-conflict guard. Wired into CI.

git-bash's mktemp returns MSYS paths like /tmp/zachflow-demo-config-XXXX, which Windows-native python3 cannot resolve (FileNotFoundError). Pass the DEMO_SOURCE_PATH and DEMO_CONFIG through `cygpath -m` to produce mixed-mode paths (e.g. C:/.../tmp/foo) that both git-bash and native binaries accept. No-op on macOS / Linux.

demo-mode-test.sh hands $STAGE/sprint-config.yaml to python3 to verify role.source wiring. On Windows runners, git-bash mktemp produces an MSYS path that python3 can't open. Mirror the to_native_path helper from init-project.sh inside the test so $TMPDIR is mixed-mode from the start. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
bash scripts/init-project.sh --demosynthesizes a throwaway Node.js source repo in a temp dir, wires a single backend role at it, and runs the rest of the wizard non-interactively. Zero prompts.templates/demo-source/(3-file scratch: greet() module + test + package.json + README) is the source-of-truth for the throwaway repo.rm -rfcommand.--demois mutually exclusive with--from=<file>(the demo synthesizes its own config).tests/demo-mode-test.shcovers the happy path, throwaway-repo correctness, banner content, and the flag-conflict guard.Why
Install/setup UX review M-4: a new user evaluating zachflow couldn't try it without already having a target codebase pointed at by a
source:path ininit.config.yaml. The barrier to first impression was too high.--demoremoves that barrier — paste one command, get a fully-running zachflow project + a sample to point/sprintat.Test plan
