📖 [Docs]: Coding style guides now live in the docs site

[Marius Storhaug (MariusStorhaug)]

The PSModule coding style guides now live in the documentation site under a new Style Guides menu section. Contributors and agents can browse the GitHub Actions, Markdown, and PowerShell conventions directly on the docs site instead of digging through editor instruction files in another repository.

New: Style Guides section in the docs

A new Style Guides entry appears in the top navigation, containing:

• GitHub Actions — workflow and composite action authoring conventions: job/step naming, quoting, SHA pinning, minimal permissions, OIDC and secrets handling, untrusted-input safety, trigger isolation, runner pinning, and a zizmor security checklist.
• Markdown — headings, lists, code blocks, links, tables, emphasis, whitespace, and filename conventions.
• PowerShell — One True Brace Style, naming, parameters, error handling, pipeline design, performance, and Pester testing conventions.

Each guide states the rule, shows good and bad examples, and explains how to apply it. The Markdown and PowerShell guides are migrated verbatim from the editor instruction files that previously lived in the Process-PSModule repository; the GitHub Actions guide is new and aligns with the existing GitHub Actions Standard.

Technical Details

• Added src/docs/Style-Guides/ with index.md, GitHub-Actions.md, Markdown.md, and PowerShell.md.
• Editor-specific frontmatter (applyTo) was replaced with docs frontmatter (title/description).
• Registered the new Style Guides section in the nav array in src/zensical.toml, placed between GitHub Actions and Solutions.
• Companion PR: PSModule/Process-PSModule#349 removes the now-migrated instruction files.
