feat(v1.49.0): tests/ → test-cases/ rename, test case terminology, landing page rewrite

Phase 1 — Folder Rename:
- Default output dir changed from tests/ to test-cases/ in TestsConfig, InitHandler,
  config template, and all fallback strings across CLI/MCP handlers
- Updated CI workflow templates, test fixtures, and 20+ test files
- All 1706 tests pass (514 Core + 841 CLI + 351 MCP)

Phase 2 — Terminology Sweep:
- Standardized "test case(s)" across 12 SKILL files, 2 agent files, 15+ docs
- Updated constitution (v1.1.0), PROJECT-KNOWLEDGE, README, CLAUDE.md
- Preserved compound terms (test run, test suite, test ID, test data)

Phase 3 — Landing Page:
- Rewrote docs/index.md with comparison table, Chat-first workflow, quick install

Phase 4 — CLI-vs-Chat:
- Replaced 4800-word analysis with 146-word page (Chat = recommended, CLI = engine)

Breaking change: default tests.dir now "test-cases/" (zero external users)

-SPECTRA is an AI-native test case generation, execution, coverage analysis, and maintenance CLI tool. It reads product documentation, extracts testable behaviors, generates structured manual test cases (as Markdown files with YAML frontmatter), executes them through an MCP server with AI agent orchestration, and produces coverage reports and dashboards.
