Corrections to mcp/execution environments

[ianf77]

Testathon changes to MCP servers and execution environments.

https://redhat.atlassian.net/browse/AAP-72785

[fistilis]

Hey Ian, thanks for the PR. I reviewed against the feedback from AAP-73188 and the testathon notes — a few items need attention before this can merge.

Regressions introduced by this PR

1. pyoi typo introduced: In ref-evaluate-mcp-servers.adoc, the change goes from lang: "pypi" to lang: "pyoi" — this introduces the typo into the security best practices section rather than fixing it. The original pyoi typo in the installation method table (in ref-mcp-builder-collection.adoc) also still needs to be corrected to pypi.

2. mkdir command is still wrong: The fix uses square brackets [defaults,tasks,meta] instead of curly braces {defaults,tasks,meta}, and removes roles/cfn_mcp/ from the path. The correct command should be:

   mkdir -p collections/ansible_collections/myorg/mcp_cfn/roles/cfn_mcp/{defaults,tasks,meta}
   

3. Version string 1.0.1.9 should be 1.0.19: All version updates use a four-segment version (1.0.1.9) instead of the correct three-segment semver 1.0.19. Affects galaxy.yml, defaults/main.yml, dependency field, and security best practices.

4. Final tarball reference still says 1.0.0: End of proc-create-custom-mcp-server-role.adoc still has myorg-mcp_cfn-1.0.0.tar.gz — should be 1.0.19 to match.

5. Mismatched quotes on manifest path: The fix for the concatenated path uses a backtick to open and a single quote to close: `/opt/mcp/mcpservers.json'). Should use matching backticks.

6. Double backtick still present: install_manager`` task — the errant double backtick from the original is still there.

Still outstanding from AAP-73188

• "built-in" → "dev preview": Section 6.6 references "built-in Model Context Protocol (MCP)" — should say "dev preview" per product positioning.
• Invalid lang type downstream failure: Docs say "install manager skips installation" but generate_manifest.yml then fails with 'dict object' has no attribute 'path' (rc=2). Either document this downstream failure or note it as a known limitation.
• Directory structure shows files no command creates: The structure diagram shows galaxy.yml, README.md, LICENSE, and main.yml files, but no documented command creates them. This is misleading for someone following step-by-step.
• Role name inconsistency: Role name switches from cfn_mcp to mcp_cfn at step 7, breaking copy-paste flow.
• AsciiDoc rendering issues: Section 6.7 has "ote" (part of "remote") greyed out; sections 6.8 and 6.11 have +/* characters that should render as bullets.
• Remote mode wording contradiction: The main text still says "skips installation" right before the new NOTE saying the package is still installed. Suggest rewording the main text itself rather than contradicting it with a note.
