fix: audit bugs + better error logging for searcher debugging

Bugs fixed:
- form_filler.mjs: add missing await on el.evaluate() in getLabel()
- analyze_ats.mjs: check job.apply_type instead of non-existent job.easy_apply
- status.mjs: fix typo "that run" → "in that run"
- README: add missing lock.mjs to project structure

Logging improvements:
- job_searcher.mjs: log browser creation, login steps, stack traces on error
- linkedin.mjs/wellfound.mjs: catch and log navigation failures per keyword
- browser.mjs: descriptive errors for Kernel and CDP connection failures
