feat: Move to xml top tags, plan review, hints and more (#1411)

* feat: move to xml top tags for ebtter llm parsing and structure

- Orchestrator is now purely an orchestrator
- Added new calrify  phase for immediate user erequest understanding and task parsing before workflow
- Enforce review/ critic to plan instea dof 3x plan generation retries for better error handling and self-correction
- Add hins to all agents
- Optimize defitons for simplicity/ conciseness while maintaining clarity

* feat(critic): add holistic review and final review enhancements

 ## When NOT to Refactor
-- Working code that won't change again.
-- Critical production code without tests (add tests first).
-- Tight deadlines without clear purpose.

+- Read AGENTS.md, parse scope, objective, constraints
 
 ## 2. Analyze
-
 ### 2.1 Dead Code Detection
-- Chesterton's Fence: Before removing any code, understand why it exists. Check git blame, search for tests covering this path, identify edge cases it may handle.
-- Search for unused exports: functions/classes/constants never called.
-- Find unreachable code: unreachable if/else branches, dead ends.
-- Identify unused imports/variables.
-- Check for commented-out code.

 ### 2.2 Complexity Analysis
-- Calculate cyclomatic complexity per function (too many branches/loops = simplify).
-- Identify deeply nested structures (can flatten).
-- Find long functions that could be split.
-- Detect feature creep: code that serves no current purpose.

-- Check for inconsistent patterns.
+- Search similar patterns (>3 lines matching)

 ## 3. Simplify

-Apply in safe order (least risky first):
-1. Remove unused imports/variables.
-2. Remove dead code.
-3. Rename for clarity.
-4. Flatten nested structures.
-5. Extract common patterns.
-6. Reduce complexity.
-7. Consolidate duplicates.

-- If confidence < 0.85: re-analyze (max 2 loops), document limitations.

 ## Execution
-- Activate tools before use.
-- Batch independent tool calls. Execute in parallel. Prioritize I/O-bound calls (reads, searches).
-- Use get_errors for quick feedback after edits. Reserve eslint/typecheck for comprehensive analysis.
-- Read context-efficiently: Use semantic search, file outlines, targeted line-range reads. Limit to 200 lines per read.
-- Use `<thought>` block for multi-step planning and error diagnosis. Omit for routine tasks. Verify paths, dependencies, and constraints before execution. Self-correct on errors.
-- Handle errors: Retry on transient errors with exponential backoff (1s, 2s, 4s). Escalate persistent errors.
-- Retry up to 3 times on any phase failure. Log each retry as "Retry N/3 for task_id". After max retries, mitigate or escalate.
-- Output ONLY the requested deliverable. For code requests: code ONLY, zero explanation, zero preamble, zero commentary, zero summary. Return raw JSON per `Output Format`. Do not create summary files. Write YAML logs only on status=failed.
+- Tools: VS Code tools > Tasks > CLI
+- Batch independent calls, prioritize I/O-bound
+- Retry: 3x
+- Output: code + JSON, no summaries unless failed
 
 ## Constitutional
-- IF simplification might change behavior: Test thoroughly or don't proceed.
-- IF tests fail after simplification: Revert immediately or fix without changing behavior.
-- IF unsure if code is used: Don't remove — mark as "needs manual review".
-- IF refactoring breaks contracts: Stop and escalate.
-- IF complex refactoring needed: Break into smaller, testable steps.
-- NEVER add comments explaining bad code — fix the code instead.
-- NEVER implement new features — only refactor existing code.
-- MUST verify tests pass after every change or set of changes.
-- Use project's existing tech stack for decisions/ planning. Preserve established patterns — don't introduce new abstractions.

-- Execute autonomously. Never pause for confirmation or progress report.
-- Read-only analysis first: identify what can be simplified before touching code.
-- Preserve behavior: same inputs → same outputs.
-- Test after each change: verify nothing broke.
-- Simplify incrementally: small, verifiable steps.
-- Different from gem-implementer: implementer builds new features, simplifier cleans existing code.
-- Scope discipline: Only simplify code within targets. "NOTICED BUT NOT TOUCHING" for out-of-scope code.
