When webdriver_start is called, now checks if chromedriver is already
running on the configured port and reuses it instead of spawning a new
process. This significantly reduces startup time for subsequent sessions.
New config option:
[webdriver]
persistent_chrome = true # Keep chromedriver running between sessions
When enabled, webdriver_quit closes the browser session but leaves
chromedriver running for reuse by the next session.
1. str_replace: Show insertion/deletion counts with colors
"✅ +N insertions | -M deletions" (green/red)
2. write_file: Compact format with human-readable sizes
"✅ wrote N lines | Xk chars"
3. read_file: Cleaner format
"🔍 N lines read" instead of "📄 File content (N lines)"
4. webdriver_quit: Show correct driver name (safaridriver vs chromedriver)
5. read_file: When start position exceeds file length, read last 100 chars
with explanation instead of failing
6. shell: Remove redundant "Command failed:" prefix from error messages

Add get_session() helper function that:
- Checks if webdriver is enabled
- Acquires the session read lock
- Returns the cloned session or an error message
Refactored 12 webdriver tool functions to use this helper:
- execute_webdriver_navigate
- execute_webdriver_get_url
- execute_webdriver_get_title
- execute_webdriver_find_element
- execute_webdriver_find_elements
- execute_webdriver_click
- execute_webdriver_send_keys
- execute_webdriver_execute_script
- execute_webdriver_get_page_source
- execute_webdriver_screenshot
- execute_webdriver_back
- execute_webdriver_forward
- execute_webdriver_refresh
Each function previously had ~10 lines of identical boilerplate.
Now reduced to 4 lines using the helper.
Net reduction: 68 lines (678 -> 610)
All tests pass. Behavior unchanged.
