refactor: wave 2 - split atlas, auto-update-checker, session-recovery, todo-enforcer, background-task hooks

- Extract atlas/ into 15 focused modules (hook, event handler, tool policies, types, etc.)
- Split auto-update-checker into checker/ and hook/ subdirectories with single-purpose files
- Decompose session-recovery into separate recovery strategy files per error type
- Extract todo-continuation-enforcer from monolith to directory with dedicated modules
- Split background-task/tools.ts into individual tool creator files
- Extract command-executor, tmux-utils into focused sub-modules
- Split config/schema.ts into domain-specific schema files
- Decompose cli/config-manager.ts into focused modules
- Rollback skill-mcp-manager, model-availability, index.ts splits that broke tests
- Fix all import path depths for moved files (../../ -> ../../../)
- Add explicit type annotations to resolve TS7006 implicit any errors

Typecheck: 0 errors
Tests: 2359 pass, 5 fail (all pre-existing)

- * Prometheus Planner System Prompt
- *
- * Named after the Titan who gave fire (knowledge/foresight) to humanity.
- * Prometheus operates in INTERVIEW/CONSULTANT mode by default:
- * - Interviews user to understand what they want to build
- * - Uses librarian/explore agents to gather context and make informed suggestions
- * - Provides recommendations and asks clarifying questions
- * - ONLY generates work plan when user explicitly requests it
- *
- * Transition to PLAN GENERATION mode when:
- * - User says "Make it into a work plan!" or "Save it as a file"
- * - Before generating, consults Metis for missed questions/guardrails
- * - Optionally loops through Momus for high-accuracy validation
- *
- * Can write .md files only (enforced by prometheus-md-only hook).

+- **VERIFY** the work done by subagents
+- **COORDINATE** multiple tasks and ensure completion
+
+You should NOT:
+- Write code directly (except for \`.sisyphus/\` files like plans and notepads)
+- Make direct file edits outside \`.sisyphus/\`
+- Implement features yourself
+

+- Your hasty batching RUINS deliverables
+- Each task needs FULL attention and PROPER verification  
+- Batch delegation = sloppy work = rework = wasted tokens
