docs(skills): refresh tailscale-topology host inventory

[DJRHails]

Refreshes the (transcrypt-encrypted) tailnet inventory skill — one node's entry was stale after it re-registered, plus a previously undocumented host row. Details are inside the encrypted file.

Review Summary

Post-merge review (the PR merged as 704bd8c9 before this review ran). The changed file is transcrypt-encrypted and this reviewer runs without the decryption key, so the review covered encryption integrity and plaintext metadata rather than the inventory content itself.

Findings

#	Severity	Finding	Resolution
1	P3	The head branch name embeds a tailnet hostname that appears nowhere else in the repo's plaintext — the exact class of detail the encrypted file exists to hide, and it identifies which node the deliberately-generic PR body refers to. The remote branch is already deleted, but GitHub retains a merged PR's head branch name permanently, so it cannot be scrubbed.	Prevention landed: PR #52 extends the encrypted-at-rest Git Hygiene rule in modules/agents/AGENTS.md to cover branch names (they must be generic before the first push, since there is no after-the-fact fix).

No inline comments: the diff is ciphertext, and the single finding is about PR metadata, not a diff line.

What was verified

• Committed blob at modules/agents/skills/tailscale-topology/SKILL.md is proper transcrypt ciphertext (Salted__ header) — no plaintext escaped into the commit.
• Commit message, PR title, and PR body are appropriately generic — no inventory details leaked there.
• Hostname sweep across all tracked plaintext files and commit messages confirmed the branch-name disclosure is the only new exposure.
• scripts/check-crypt-patterns.sh: pass. gitleaks (staged) and trufflehog (filesystem): no leaks on the fix change.

Commit

Fix pushed as e3ab932 on PR #52 — docs(agents): extend encrypted-at-rest rule to branch names.
