Ship the full required baseline file set in the module template

[MariusStorhaug]

Problem

PSModule/Template-PSModule is the canonical starting point for new PowerShell module repositories, but it does not ship the full baseline file set that Repository Defaults requires of every module repository. A repository created from the template is immediately non-compliant with the documented standard, and every new module repository starts with a manual cleanup task.

This was found while creating PSModule/Lovdata from the template.

Missing files

Compared to the "Required common files" table in Repository Defaults, the template is missing:

• SECURITY.md — private vulnerability reporting and latest-version support policy.
• SUPPORT.md — support channel and issue-routing expectations.
• CODE_OF_CONDUCT.md — community participation rules.
• .github/pull_request_template.md — PR Manager-compatible pull request template.

Repository Defaults also lists .github/copilot-instructions.md, but that entry is stale. AGENTS.md at the repository root is the agent entry point and is read natively by the runtimes, so the template intentionally does not carry a Copilot-only pointer file. Tracked in PSModule/docs#102.

Why the organization fallback is not enough

Repository Defaults is explicit that each repository must stand on its own and must not rely on the organization .github fallback: agents, linters, Dependabot, CODEOWNERS, and release automation read repository-local files, while the org fallback is only surfaced in GitHub's web UI.

Desired outcome

A repository generated from the template is compliant on the first commit, with no manual additions.

Acceptance criteria

• SECURITY.md, SUPPORT.md, CODE_OF_CONDUCT.md, and .github/pull_request_template.md exist in the template.
• The files are generic and token-free, so they work as-is in a generated repository.
• Wording is consistent with the existing PSModule community files rather than newly invented.
• The repository linter passes on the new files.
