fix: Resolve ADR/Requirements inconsistencies from comprehensive review

## ADR Compliance Section Fixes

- ADR-007: Fixed invalid NFR-501 and TC-002 references
  - NFR-501 → NFR-402 (Fault tolerance)
  - TC-002 → Core Principle (self-hostability)

- ADR-008: Fixed invalid NFR-501 reference
  - Added TC-006 (pgvector extension)

- ADR-011: Fixed invalid FR-201-205 and NFR-201 references
  - Now correctly references FR-401-404 (Issue Tracking series)

- ADR-012: Fixed invalid FR-401, FR-402, NFR-302 references
  - Now references new FR-800 series (Cost & Budget Management)

- ADR-014: Fixed invalid FR-601-605 and FR-102 references
  - Now correctly references FR-203 (Autonomy Level Configuration)

## ADR-007 Model Identifier Fix

- Changed "claude-sonnet-4-20250514" to "claude-3-5-sonnet-latest"
- Matches documented primary model (Claude 3.5 Sonnet)

## New Requirements Added

- FR-801: Real-time cost tracking
- FR-802: Budget configuration (soft/hard limits)
- FR-803: Budget alerts
- FR-804: Cost analytics

This resolves all HIGH priority inconsistencies identified by the
4-agent parallel review of ADRs against requirements and architecture.
