fix(ui): sanitize process output before terminal rendering

[maful]

Summary

Process output and display metadata could reach Model.View() with arbitrary terminal control sequences intact. A process that emitted OSC or CSI controls could manipulate supported terminal state, including the window title, screen, or clipboard.

This change:

• sanitizes log lines before retention, search indexing, and rendering
• preserves bounded conventional SGR color and style sequences
• removes OSC, DCS, APC, PM, SOS, cursor, screen, C0/C1, malformed, and incomplete control sequences
• resets retained styles at log-line boundaries
• sanitizes display-only process names, commands, paths, branches, and versions
• keeps the original Procfile commands unchanged for execution
• adds regression coverage for filtered and unfiltered rendering
