v0.12.0

Added

• xcompare MCP tool: compare variable states at the same breakpoint across two PHP executions (#91).
• xcoverage now defaults to a compact AI-first report (coverage percent + uncovered lines per file); --json keeps the schema-backed JSON (#91).

Changed

• xcoverage: STDOUT carries only the coverage report; the target program's own output and failed PHPUnit output go to STDERR (#91).
• tools/call responses surface execution error messages instead of a bare "No result" (#91).
• Extract PhpCommandParser and CachegrindAnalyzer from CLI scripts into unit-testable classes (#91).
• Commit messages no longer use Conventional Commits prefixes (#91).

Fixed

• xcompare rejects comma-separated breakpoint lists instead of silently mis-parsing them (#91).
• findScriptIndex() returns false for inline code (-r/--run) instead of treating the code as a script file (#91).
• Cachegrind analysis resolves Callgrind-style bare fn=(id) aliases instead of dropping their costs, and counts PDO static calls as database operations (#91).
• Japanese locale detection matches ja as a primary language tag (no more Azerbaijani false positive), with POSIX priority order (LC_ALL → LC_MESSAGES → LANG) and macOS AppleLanguages fallback (#91).
• DbgpXml::sanitize() preserves U+007F, consistent with isXmlCharacter() (#91).
• xcoverage exits non-zero when the coverage payload is missing or corrupt instead of inheriting the target's exit status (#91).
• Cross-platform claude CLI detection via PATH lookup instead of a hard-coded macOS path (#91).
