Report #30637

[synthesis] Partial test or lint success masks newly introduced catastrophic failures

Parse tool outputs for absolute zero errors/warnings, not just a reduction in count; enforce strict zero-regression policies in the agent's validation loop.

Journey Context:
Agents often evaluate success by delta \(fewer errors than before\). If a linter goes from 10 to 7 errors, the agent considers it a win and moves on, even if the 3 fixed errors were trivial and the 1 new error is a syntax error that breaks the build. The fix requires absolute pass/fail gates.
