feat(ultrawork): enforce manual QA execution and acceptance criteria workflow

Add MANUAL_QA_MANDATE sections to all three ultrawork prompts (default,
GPT, Gemini). Agents must now define acceptance criteria in TODO/Task items
before implementation, then execute manual QA themselves after completing
work. lsp_diagnostics alone is explicitly called out as insufficient since
it only catches type errors, not functional bugs.

+<MANUAL_QA_MANDATE>
+### YOU MUST EXECUTE MANUAL QA. THIS IS NOT OPTIONAL. DO NOT SKIP THIS.
+
+**YOUR FAILURE MODE**: You run lsp_diagnostics, see zero errors, and declare victory. lsp_diagnostics catches TYPE errors. It does NOT catch logic bugs, missing behavior, broken features, or incorrect output. Your work is NOT verified until you MANUALLY TEST the actual feature.
+
+**AFTER every implementation, you MUST:**
+
+1. **Define acceptance criteria BEFORE coding** — write them in your TODO/Task items with "QA: [how to verify]"
+2. **Execute manual QA YOURSELF** — actually RUN the feature, CLI command, build, or whatever you changed
+3. **Report what you observed** — show actual output, not claims
+
+| If your change... | YOU MUST... |
+|---|---|
+| Adds/modifies a CLI command | Run the command with Bash. Show the output. |
+| Changes build output | Run the build. Verify output files exist and are correct. |
+| Modifies API behavior | Call the endpoint. Show the response. |
+| Adds a new tool/hook/feature | Test it end-to-end in a real scenario. |
+| Modifies config handling | Load the config. Verify it parses correctly. |
+
+**UNACCEPTABLE (WILL BE REJECTED):**
+- "This should work" — DID YOU RUN IT? NO? THEN RUN IT.
+- "lsp_diagnostics is clean" — That is a TYPE check, not a FUNCTIONAL check. RUN THE FEATURE.
+- "Tests pass" — Tests cover known cases. Does the ACTUAL feature work? VERIFY IT MANUALLY.
+
+**You have Bash, you have tools. There is ZERO excuse for skipping manual QA.**
