[FEATURE] Per-tab IDE context isolation in VS Code extension

Problem Statement

When running multiple chat tabs in the VS Code extension, all tabs share the same ide_opened_file context. If I'm working with a file in Tab A, then switch to Tab B (an unrelated conversation), Tab B sees that file as the currently open file and may start commenting on it or offering to help with it.

This causes cross-talk between conversations — tabs react to files that have nothing to do with their context.

Proposed Solution

Scope the ide_opened_file context to the tab that was active when the file was opened/viewed, rather than broadcasting it to all tabs. Each chat tab should only see file context relevant to its own conversation.

Alternative Solutions

A simpler alternative: only inject ide_opened_file into the tab the user is currently interacting with, and suppress it for background tabs entirely.

Medium - Would be very helpful
