Adds the local task runner required by
docs/governance/repository-bootstrap-plan.md v0.1.0 §3, with stubs
for format, lint, test, verify-docs, and security-scan.
Closes the last gap in repository-bootstrap-plan v0.1.0; CI workflow
files remain deferred per the plan.
Imports the v0.9.2 documentation baseline and the bootstrap files
required by docs/governance/repository-bootstrap-plan.md v0.1.0 §3,
minus the justfile (added in the next commit).
This commit establishes the git history for the project. All previous
work lived only as filesystem state with no version control.
