[test] docsUrl anchor not actually fetched — README rewording could silently break recovery URL

[kiki830621]

Problem

che-telegram-all-mcp-wrapper.sh:125 docsUrl hardcodes #multi-session-limitation anchor. Logic Reviewer verified by mental algorithm only — no curl test, no test-script assertion. Future README rewording (em-dash in title, CJK translation, duplicate section name) could silently break the URL.

Surfaced by Devil's Advocate (Challenge #4 LOW).

Expected

Add 5-line test:

test_case "test_docsUrl_anchor_exists_in_readme"
README="$SCRIPT_DIR/../README.md"
DOCS_URL=$(grep -oE '"docsUrl":"[^"]+' "$WRAPPER" | head -1)
ANCHOR="${DOCS_URL##*#}"
SECTION_TITLE=$(grep '^## ' "$README" | sed 's/^## //; s/ /-/g' | tr 'A-Z' 'a-z')
echo "$SECTION_TITLE" | grep -q "^${ANCHOR}$" && pass "anchor matches" || fail "anchor missing"

Priority

P3 — regression sentinel.
