Three defects in the completing-milestone dispatch guard caused false
positive blocks on valid validation output:
1. Single-line constraint: [^\n]* stopped at newlines, missing verdicts
on subsequent lines. Fixed with [\s\S]{0,500}? (bounded lazy match).
2. Missing keywords: 'satisfied' and 'partially' were absent from the
alternation. LLMs commonly write 'PARTIALLY SATISFIED' or 'FULLY
SATISFIED'. Added both.
3. Markdown bold delimiters: **Operational** blocked [\s:] after the
word. The new [\s\S] class handles any character including *.
Also adds SATISFIED to the structuredMatch includes check, and ✅ to
the prose regex (overlaps with #2862).
Includes 8 regression test cases covering multi-line formats, satisfied
keyword variants, markdown bold tables, and checkmark emoji.
