Subject: [PATCH] fix: detect Claude Code native binary via resolved Exe path

The native Claude Code binary installs to ~/.local/share/claude/versions/<ver>
and is symlinked from ~/.local/bin/claude. On macOS, gopsutil reports the
cmdline as just "claude" (the symlink name) without the full path, so the
existing node_modules-based IDE signatures don't match.

Add Exe field to ProcessInfo (resolved binary path from gopsutil p.Exe())
and check it alongside Cmdline in IDE signature matching. Add a
/.local/share/claude/ path signature for the native install.

Without this fix, parent_ide_dead (0.30) fires on all MCP servers even
when Claude Code is running, pushing servers with has_listener above the
kill threshold.

Closes #8
