UnityLeanMcp v0.8.0-preview.14

feat: Bump version to 0.8.0-preview.14

refactor: simplify polling loop, eliminate refresh latency tax, and streamline process verification

• Decouple process liveness inspection from active 500ms polling loop, querying process table only on socket transport failure
• Return terminal results immediately from custom response handler on READY/COMPILATION_ERROR, eliminating 500ms delay
• Streamline batchmode identity verification to read typed store in single pass
• Eliminate redundant duplicate socket readiness probes on process startup
• Support relative -projectPath arguments (. and ./) in CommandLineTargetsProject
• Broaden compiler error diagnostic regex to support UPM package paths (@) and Unicode
• Update DESIGN.md and LEARNINGS.md with new architectural decisions and edge cases

fix: harden multiplatform process discovery, lockfile handling, and argument parsing

• Fix macOS sysctl(KERN_PROCARGS2) parsing to skip exec_path and padding, preserving all argv arguments
• Treat macOS paths as case-insensitive in PathsEqual matching default APFS/HFS+ semantics
• Resolve symlink targets when verifying process executable paths
• Never delete UnityLockfile on failed lock probe and improve GUI process liveness detection
• Update UnityLogScanner regex to detect compilation errors from package cache (@) and Unicode paths
• Trim trailing directory separators from ProjectRoot and LogFile before quoting in ProcessStartInfo
• Add default Linux Unity Hub path (~/.local/share/unity3d/Hub/Editor) to candidate discovery
• Add case-insensitive and relative path matching for .vscode/mcp.json in installer
• Document platform behaviors and edge cases in LEARNINGS.md
