docs: restore missing separator in CHANGELOG.md

The rebase of 22ff056 onto origin/main's new Docker dev workflow entry
dropped the blank-line + --- separator between that entry and the
CLAUDE.md rewrite entry, running the two together with no boundary.

 ## 2026-07-06: rewrite CLAUDE.md as an operating manual; add Claude Code project skills
 
 CLAUDE.md still described the Phase 1 scaffold ("no migration system", "do not implement Phase 2+ features"), which stopped being true over a year of shipped phases ago. Rewritten as a full operating manual so agent-assisted work (Joel's or a contributor's) follows the house process without rediscovering it: server, driver, and client conventions as exact idioms, a sync-pairs table of code that must change together, named failure modes with the rule that prevents each, per-deliverable quality checklists, and escalation rules for ambiguous cases. Also adds three project skills under `.claude/skills/`, which is now tracked (personal `.claude` settings remain ignored).
