When no chrome_binary is configured, auto-detect Chrome for Testing
at ~/.chrome-for-testing/ and use it instead of letting ChromeDriver
fall back to system Chrome. This prevents the frequent version
mismatch error caused by system Chrome auto-updating independently
of the ChromeDriver installed by setup-chrome-for-testing.sh.
Checks mac-arm64, mac-x64, and linux64 paths. Falls back to system
Chrome (previous behavior) if Chrome for Testing is not installed.
Removed the persistent_chrome config flag - chromedriver is now always
kept running after webdriver_quit. This eliminates startup latency for
subsequent WebDriver sessions.
Safaridriver is still killed on quit since it doesn't benefit from
persistence in the same way.
Updated quit message to correctly indicate chromedriver remains running.
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.
