fix: correct tautological uppercase check in tool description summarizer

Gautam Kumar · Gautam Kumar · commit 1103b96ce48e · 2026-06-17T00:41:54.000+05:30
The isToolDocBlockStart function checked normalized === normalized.toUpperCase()
but normalized is already uppercased from line 24, making the condition always true.
This caused mixed-case lines ending with ':' to be incorrectly detected as doc block
starts, truncating tool descriptions unnecessarily.

Compare the original line instead to correctly detect all-uppercase headings.
