fix --version outputting v0.0.0 and centralize VERSION as single source of truth

[JeremyDev87]

Summary

Fixes #592

npx codingbuddy --version was outputting v0.0.0 because version.utils.ts attempted to resolve package.json via readFileSync(join(__dirname, '..', '..', 'package.json')), which resolves to dist/src/package.json at runtime — a path that does not exist. The catch block silently returned '0.0.0'.

Root Cause

join(__dirname, '..', '..', 'package.json')
  → dist/src/package.json  ← does not exist
  → catch → return '0.0.0'

Changes

Core Fix (fix(version))

• Add apps/mcp-server/src/shared/version.ts — single source of truth; exports VERSION = '4.3.0'
• Refactor version.utils.ts — replace readFileSync path resolution with import { VERSION } from version.ts
• Simplify version.utils.spec.ts — remove fs mock entirely; validate semver format and VERSION constant equality instead

Scripts (feat(scripts))

• Add scripts/bump-version.sh — atomically updates version.ts and all package.json files in one command
  • Node.js-based file modification (cross-platform, no sed -i dependency)
  • Validates semver format (^[0-9]+\.[0-9]+\.[0-9]+$) before applying
  • Validates CWD is project root before running
• Update scripts/verify-release-versions.sh — include version.ts VERSION constant in release verification checks

Verification

# Build and verify
yarn workspace codingbuddy build
node apps/mcp-server/dist/src/cli/cli.js --version
# → codingbuddy v4.3.0 ✅

# Tests
yarn workspace codingbuddy test --testPathPattern=version
# → 4 tests passed ✅

# Version bump script
./scripts/bump-version.sh 4.4.0
# → Updates version.ts + 3 package.json files atomically ✅

# Release verification
./scripts/verify-release-versions.sh
# → All 4 files match v4.3.0 ✅

Test Plan

• version.utils.spec.ts — 4 tests pass (semver format, VERSION equality, fallback export)
• E2E: npx codingbuddy --version outputs codingbuddy v4.3.0
• bump-version.sh — semver validation, CWD check, atomic update of 5 files
• verify-release-versions.sh — validates version.ts alongside package.json files
