After the templates are copied, create-project.sh adds /.claude, /.agents and
/AGENTS.md to .git/info/exclude of the new project as its own step, "Git
excludes". No .gitignore or tracked file changes and nothing is committed.
The step is skipped when the framework steps are skipped, and a path git
already tracks stays tracked and is named in the step.
The .git/info/exclude code of exclude_env_file moves into the shared helper
exclude_from_git (git.sh), which both now use; the .env behavior is unchanged.

Task: MIL-009#2
S02 gave the Go in chat on 2026-10-08 and waived the PlantUML render check
(no PlantUML server is configured). Add the review record RC-032, set the
latest Version History rows of MIL-009 and the changed documents to Accepted
and the rows before them to Deprecated, and record the review in the
traceability matrix.
