refactor(workflow): remove all .active marker file references and sync documentation

Core Changes (10 files):
- commands: cli/execute.md, memory/docs.md, workflow/review.md, workflow/brainstorm/*.md
- agents: cli-execution-agent.md
- workflows: task-core.md, workflow-architecture.md

Transformations:
- Removed all .active-* marker file operations (touch/rm/find)
- Updated session discovery to directory-based (.workflow/sessions/)
- Updated directory structure examples to show sessions/ subdirectory
- Replaced marker-based state with location-based state

Reference Documentation (57 files):
- Auto-synced via analyze_commands.py script
- Includes all core file changes
- Updated command indexes (all-commands.json, by-category.json, etc.)

Migration complete: 100% .active marker references removed
Session state now determined by directory location only

 ## Overview
 
-Systematically enhances user prompts by combining session memory context with codebase patterns, translating ambiguous requests into actionable specifications.
+Systematically enhances user prompts by leveraging session memory context and intent analysis, translating ambiguous requests into actionable specifications.

 **Enhancement Pipeline:**
-`Intent Translation` → `Context Integration` → `Gemini Analysis (if needed)` → `Structured Output`
+`Intent Translation` → `Context Integration` → `Structured Output`
 
 **Context Sources:**
 - Session memory (conversation history, previous analysis)
-- Codebase patterns (via Gemini when triggered)
 - Implicit technical requirements

+**Session Memory:**
 - Reference recent conversation context
 - Reuse previously identified patterns
 - Build on established understanding

-**Codebase Analysis (via Gemini):**

-- Focus on integration points
-- Identify existing patterns
+- Infer technical requirements from discussion
 
 **Example:**
 ```bash
 # User: "add login"
 # Session Memory: Previous auth discussion, JWT mentioned
 # Inferred: JWT-based auth, integrate with existing session management
-# Gemini (if multi-module): Analyze AuthService patterns, middleware structure
+# Action: Implement JWT authentication with session persistence

 ## Key Principles
 
-1. **Memory First**: Leverage session context before analysis
-2. **Minimal Gemini**: Only when complexity demands it
-3. **Context Reuse**: Build on previous understanding
-4. **Clear Output**: Structured, actionable specifications
