[CRITICAL] Fix typos and grammar errors across codebase and documentation

[AVPthegreat]

Problem: Typos and grammatical errors present in:\n- README.md\n- CONTRIBUTING.md\n- Code comments\n- UI text (button labels, error messages, form placeholders)\n- Log messages\n\nImpact:\n- Reduces professional perception of the project\n- May confuse contributors or users\n- Makes documentation harder to follow\n\nScope:\nConduct a full audit of all user-facing text:\n1. Documentation files (README, CONTRIBUTING, SECURITY, etc.)\n2. UI templates (index.html, job.html, recent.html)\n3. Error messages and API responses\n4. Code comments (especially public functions)\n5. Log output\n\nTools:\n- Run a spell checker (VS Code spell check extension)\n- Use Grammarly or LanguageTool for grammar\n- Manual review of technical terminology\n\nAcceptance Criteria:\n- ✅ All documentation files pass spell check\n- ✅ UI text is grammatically correct and professional\n- ✅ Error messages are clear and actionable\n- ✅ Code comments use consistent terminology\n- ✅ No embarrassing typos in public-facing pages\n- ✅ Add .vscode/settings.json with spell check enabled + custom dictionary for technical terms\n\nPriority: P0 - Easy fix with high ROI for professionalism\n\nGood First Issue: Perfect for new contributors; low complexity, high impact.

Hi! I would like to work on this issue.

I’ll run a spell/grammar audit on:

• README.md
• CONTRIBUTING.md
• UI text labels
• Code comments

I will keep the tone consistent and professional, and include a .vscode spell-check configuration if needed.

Please assign me — I’ll submit a clean PR shortly.
