Add full driller-bosun update

[DenysKuchma]

Summary

This PR improves the Driller flow and expands the reusable experience set for custom UI components. #15

Changes

• Added drill CLI/TUI command support and renamed Bosun-related code to Driller.
• Improved Driller component discovery and interaction handling:
  • prioritizes main page components before secondary navigation links
  • improves handling for custom controls like toggles, tabs, inputs, code inputs, date ranges, PowerSelect variants, and tag inputs
  • adds better metadata/context for similar repeated components
  • avoids relying on container locators in generated drill actions
• Added and cleaned reusable experience files for the tested component pages.
• Added URL query support in state/path matching so component pages like ?m=false&s=... are handled correctly.
• Improved element annotation metadata, including iframe handling and richer raw element context.
• Removed remaining Bosun references from code/docs.
• Removed legacy --max support; Driller now uses --max-components only.
• Fixed reporter output for ad-hoc ExplorBot tests:
  • tests that pass verified notes now receive a proper PASSED result
  • HTML report generation now includes completed ExplorBot tests instead of producing an empty report

Tests

• Added unit coverage for Driller element metadata behavior.
• Added reporter coverage to verify HTML report output contains completed ExplorBot tests.
