Hacktoberfest-ready: CONTRIBUTING.md + issue templates

[naimkatiman]

Description

Make TradeClaw fully contribution-ready with a proper CONTRIBUTING.md guide, issue templates, and PR template.

• Issue templates: bug report, feature request, question
• PR template with checklist
• Add "Contributors" section to README with all-contributors bot
• Add hacktoberfest topic to repo
