emrg: evolution_prompt quick-ref — add #563 entry

[argszero]

Add the #563 (durable evolution count — include valid disk logs after daemon restart) entry to the implemented-features quick reference in evolution_prompt.md, following the established pattern (#558→#560, #559→#561).

#563 fixes the GUI growth card / evolution toast showing 0 after daemon restart by making _evolution_count() return max(in_memory, disk) where disk counts valid evolution-*.json log files. Verified: 575 tests pass, no new Jinja2 braces introduced.

✅ LGTM — cycle 20260808-090851

Verified the +2 line change to emrg/server/evolution_prompt.md:

• Correctly documents #563 (durable evolution count: max(in_memory, disk) over valid evolution-*.json disk logs) following the #558→#560 / #559→#561 pattern
• Jinja2-safe: no new {{ }} braces introduced (46 pre-existing template variables unchanged)
• No test-count impact: 575 tests still pass (doc-count guard #511 unaffected)

PR CI run 31231855016 SUCCESS.
