feat: installer detects Python version and warns when 3.11+ (tomllib) is missing (#2466)
* feat: installer detects Python version and warns when 3.11+ (tomllib) is missing

Several BMAD features need Python at runtime: memlog (3.8+) and the TOML
config resolution scripts (3.11+ for stdlib tomllib). Users install into
varied environments (Linux, Windows, WSL, Docker) where Python may be
missing or too old, and previously only found out via runtime errors.

The installer now probes PATH at startup (py -3 / python3 / python) and
classifies the result: 3.11+ passes silently with a success line; 3.8-3.10
or missing/too-old Python gets a warning naming exactly which features
degrade, plus per-platform install hints. The warning requires an explicit
ack — continue (fix later, no reinstall needed) or quit and re-run after
installing Python. Warn-don't-block: most of BMAD works without Python, so
the install is never refused. In --yes mode the warning logs and continues
without prompting.

* fix: align Python check with runtime truth (python3) and harden edge cases

Review fixes for the installer Python check:

- Probe python3 first on all platforms: every runtime call site invokes a
  literal python3, so only that command vouches for BMAD features. Python
  found via py/python now gets an explicit mismatch warning instead of a
  false "all BMAD features supported".
- Treat closed/piped stdin as non-interactive (in addition to --yes) so
  scripted installs no longer silently exit 0 via clack's cancel path.
- Retry probes with shell:true on win32 EINVAL (CVE-2024-27980 hardening
  rejects .bat/.cmd shims like pyenv-win's without a shell).
- Add Suite 46 branch tests for checkPythonEnvironment with stubbed
  detection, prompts, and process.exit.

BMad CLI Tool

Installing external repo BMad official modules

For external official modules to be discoverable during install, ensure an entry for the external repo is added to external-official-modules.yaml.

For community modules - this will be handled in a different way. This file is only for registration of modules under the bmad-code-org.

Post-Install Notes

Modules can display setup guidance to users after configuration is collected during npx bmad-method install. Notes are defined in the module's own module.yaml — no changes to the installer are needed.

Simple Format

Always displayed after the module is configured:

post-install-notes: |
  Thank you for choosing the XYZ Cool Module
  For Support about this Module call 555-1212  

Conditional Format

Display different messages based on a config question's answer:

post-install-notes:
  config_key_name:
    value1: |
      Instructions for value1...      
    value2: |
      Instructions for value2...      

Values without an entry (e.g., none) display nothing. Multiple config keys can each have their own conditional notes.

Example: TEA Module

The TEA module uses the conditional format keyed on tea_browser_automation:

post-install-notes:
  tea_browser_automation:
    cli: |
      Playwright CLI Setup:
        npm install -g @playwright/cli@latest
        playwright-cli install --skills      
    mcp: |
      Playwright MCP Setup (two servers):
        1. playwright    — npx @playwright/mcp@latest
        2. playwright-test — npx playwright run-test-mcp-server      
    auto: |
      Playwright CLI Setup:
        ...
      Playwright MCP Setup (two servers):
        ...      

When a user selects auto, they see both CLI and MCP instructions. When they select none, nothing is shown.
