Add zo-mengram-setup and zo-mengram-memory skills

[Zenlyte]

Description

Adds two complementary community skills for self-hosted memory on Zo:

1. zo-mengram-setup: installation, baseline configuration, auth hardening, and verification.
2. zo-mengram-memory: daily runtime workflows with gated recall/search defaults and break-glass raw fallback.

This split keeps beginner onboarding simple while allowing faster iteration on runtime workflows.

Features

• self-hosted Mengram setup and security baseline
• gated endpoint-first runtime guidance (/api/recall/gated, /api/search/gated)
• break-glass troubleshooting path (/api/recall, /api/search)
• references for API, security, architecture, and operational overview

Validation

• Ran bun install and bun validate in the skills repo.
• Existing warnings from unrelated External skills remain unchanged.

Checklist

• SKILL frontmatter valid and names match directories
• No secrets or personal credentials included
• Uses placeholders for author and user-specific values
• Structure follows allowed directories (scripts, references, assets)

@Zenlyte A few things to address before merge.

Pin the git clone.
setup.py clones from github.com/alibaizhanov/mengram at HEAD with no tag or commit pin. Please pin to a specific release tag or commit SHA so users aren't pulling arbitrary code that can change after merge.

Author placeholder.
Both SKILL.md files still have YOUR_HANDLE.zo.computer as the author. Please fill in your actual handle.

Deduplicate.
41% of this PR is identical content across the two skills. The reference docs (api.md, architecture.md, security.md) are copied verbatim in both directories, and mengram_memory.py exists in both. Pick one canonical location for the shared docs (probably setup) and remove the duplicate mengram_memory.py from setup since it belongs in the memory skill.

Happy to re-review once updated.

All three items addressed in c8b668d:

1. Pinned git clone - setup.py now clones with --branch v2.6.1 --depth 1, pinning to the latest Mengram release tag.

2. Author placeholder - Both SKILL.md files now use Zenlyte.zo.computer.

3. Deduplicated shared content - Removed 1,029 lines of duplicated content:

   • Reference docs (api.md, architecture.md, security.md) are now canonical in zo-mengram-setup/references/ only.
   • mengram_memory.py is canonical in zo-mengram-memory/scripts/ only.
   • Both SKILL.md files now include a "Shared resources/references" section cross-referencing the canonical locations.
   • overview.md remains in both since its content is skill-specific.

Ready for re-review.

Fixed the author handles back to curtastrophe.zo.computer per my actual Zo handle.
