feat: overhaul process monitoring UI - more info, tree view, details, batch ops

User feedback: '进程比较关键，以下显示太少了，需要继续优化下监控UI'

Process monitor panel was rebuilt:

1. core/monitor.py: 200 -> 500 processes, added PPID / PRI / NICE
   New ps fields: pid ppid user pcpu pmem vsz rss stat pri nice etimes times args
   Python parser: new fields ppid, pri, nice

2. ui/widgets.py MonitorPanel:
   a) Toolbar: search box + sort dropdown (CPU/MEM/PID/start/user/comm)
      + view toggle (Flat / Tree) + CPU% min filter (SpinBox 0-100%)
      + batch kill button
   b) Table: 12 columns (Flat) / 13 cols (Tree + indent col)
      PID PPID USER CPU% MEM% RSS STAT PRI NI '启动' 'CPU时间' 命令
      - Compact row height 20px (was default 30)
      - Extended selection (Ctrl/Shift multi)
      - Color highlights:
          CPU% >=80 red bg+fg bold, >=50 red fg bold, >=20 orange
          MEM% >=15 orange bg+fg bold, >=5 orange
          STAT: Z orange bg + orange-red fg bold, R green, D purple
          NI: negative green, positive orange
      - Red bg on EXTREME rows for instant visibility
   c) Tree view: builds PPID tree with ├─/└─/│ connectors;
      root processes (PID 1) at depth 0, sorted by CPU within siblings.
      Useful for 'which process is spawning these things?'
   d) Right side panel:
      - 进程详情 (QTextEdit dark theme): full PID/PPID/USER/STAT/PRI/NI/
        CPU/MEM/RSS/VSZ/etime/cputime, command, parent process name,
        child processes list (top 10)
      - 🔥 CPU TOP 5 (QListWidget dark): click to jump+select in main table
      - 💾 内存 TOP 5 (QListWidget dark): same
   e) Right-click menu enhanced:
      kill (SIGTERM) | kill -9 (SIGKILL) | batch kill (if multi-select)
      | copy PID | copy command | filter by command | view details
   f) Batch kill: collects all selected PIDs, runs 'kill p1 p2 p3 ...'
      in a single SSH call, then loops 'kill -0' to report survivors.
      One confirmation dialog lists top 10 + '还有 N 个'.
   g) Status row at bottom: 'Ctrl+A 全选, Shift+点击多选, 右键批量操作'

3. test_process_monitor.py: 5/5 tests pass with 500 rows, tree view,
   TOP 5, CPU min filter, etc.

All tests pass: core 6/6 + UI 3/3 + E2E 6/6 + terminal 5/5 + proc 5/5
Build: 57 MB single-file exe.
