Tobias GesellchenandClaude Opus 4.7 1b21e0eaa8 docs: sweep example LAN IPs to RFC-5737 documentation range 
Phase 4 of the docs portion of the rfc-5737-cleanup. Replaces all
192.168.1.x example IPs in tracked .md / .txt files with the
equivalent last-octet under 192.0.2.x.

192.168.1.x is RFC-1918 private space and routes on real networks,
which leaves readers guessing whether a documented IP is a placeholder
or a documented LAN. 192.0.2.0/24 is reserved by RFC 5737 exclusively
for documentation — readers know on sight that they're examples.

58 files touched, 551 line pairs. Includes .github issue/PR templates,
all docs/ references, example READMEs, and one script doc. No code
changes, no test changes; test files still carry the 192.168.1.x
placeholder pending Phase 2 in _/RFC-5737-cleanup/assessment.md.

Also fixed a small fallout in docs/analysis/ANONYMIZATION-SUMMARY.md
where the explanatory sentence "a reader can't tell whether
192.168.1.10 is a placeholder or a documented LAN address" had
itself been swept by the regex (inverting the point); restored the
literal example and noted the sweep progress inline.
