Removed Claude indicator from the NetBeans status bar (#95)

Backport of #94 to `release/0.21`.

## Summary

- Removed `ClaudeCodeStatusLineElement` — the "Claude ✓/~/✗" clickable
label in the NetBeans status bar
- It duplicated the stop/switch button already present in the Claude
session tab's own status bar

## Test plan

- [ ] Build and install the plugin
- [ ] Verify the Claude indicator no longer appears in the NetBeans
status bar
- [ ] Verify the session stop/switch button in the session tab still
works normally

+- Removed Claude indicator from the NetBeans status bar (duplicated the stop button in the session tab)
 - Fixed diff dialog appearing as a detached tab with disabled Cancel/Accept-All buttons when Claude edits a file outside its current working directory (e.g. after cd into a subdirectory)
 - Fixed choice menu not recognizing the Ultraplan "Tell Claude what to change" option as a text input field
 - Added "Bypass Permissions" edit mode: automatically detected when Claude is launched with `--dangerously-skip-permissions`; auto-allows all file edits without showing a diff dialog
