Summary by cubic

Adds cross-platform one-line installers for Continue CLI that auto-install Node.js 20+ when needed and streamline setup. Updates docs to auto-detect OS and show the right command, making onboarding faster.

• New Features
  • One-liners: macOS/Linux via curl to install.sh; Windows via PowerShell irm to install.ps1.
  • Auto Node setup: detects Node, installs 20.19+ with fnm if missing, persists PATH/profile, and fixes npm global permissions.
  • Better docs: OS tab auto-detect, shared CLI install snippet reused across guides/README, and updated Install/Overview pages (Node prereq now 20+).

^{Written for commit 045021a. Summary will update on new commits.}

<file name="extensions/cli/scripts/install.sh">

<violation number="1" location="extensions/cli/scripts/install.sh:149">
P2: `set -u` plus unguarded `$FNM_DIR` expansion in `source_fnm` will abort the installer when FNM_DIR is unset.</violation>

<violation number="2" location="extensions/cli/scripts/install.sh:182">
P2: Cleanup can remove an existing fnm installation because CLEANUP_FNM is set unconditionally without tracking whether the install directory pre-existed.</violation>
</file>

<file name="extensions/cli/scripts/install.ps1">

<violation number="1" location="extensions/cli/scripts/install.ps1:173">
P2: Direct-download fnm install only updates the current session PATH; no persistent PATH update is written, so new shells may not find `fnm` and the profile init will fail after restart.</violation>

<violation number="2" location="extensions/cli/scripts/install.ps1:274">
P2: User-local npm prefix is only added to the current session PATH; after restarting PowerShell the CLI may not be on PATH, so `cn` can be missing despite a successful install.</violation>

<file name="extensions/cli/README.md">

<violation number="1" location="extensions/cli/README.md:12">
P2: Docs now recommend `curl|bash`/`irm|iex` of scripts from the moving `main` branch without pinning or integrity verification, which creates a supply‑chain risk and non‑reproducible installs.</violation>

<violation number="1" location="docs/guides/posthog-github-continuous-ai.mdx:1">
P2: Frontmatter delimiter is corrupted (`20---`), so the YAML metadata won’t be parsed as frontmatter and can break MDX metadata/builds.</violation>
