Displaying PR comments directly in the code

**Is your feature request related to a problem? Please describe.**
When I want to review comments from my colleagues and apply some changes in my code, I need to switch back and forth between Atlassian's diff view - where I can see comments - and my current code view - where I can actually code.

**Describe the solution you'd like**
I'd like to have comments embedded inline in my code itself - either by some action, or tooltip, or any other UI elements allowed by VSCode.

**Describe alternatives you've considered**
Switching back and forth, but I feel like it's better to actually use web BitBucket version on a different screen, than switching back and forth.

**Additional context**
None

No files, tests, or entry points are identified in the issue. Start by locating the extension's existing Bitbucket diff and review-comment handling, then inspect the VS Code UI integration points that could display comments in the current code view. Done means reviewers can access relevant pull-request comments inline without switching to the Atlassian diff view.
