Align LongBridge runtime strategy profiles

[Pigbibi]

Summary

This aligns LongBridge with the shared six-profile runtime-enabled US equity catalog.

Cause and effect

LongBridge docs, notification labels, and tests still referenced removed research profiles as archive rows. Once the shared strategy package removed those deployable profile surfaces, those local references became stale.

Fix

• remove archived mega-cap strategy rows from README and notification localization
• update status matrix expectations around the six runtime-enabled profiles
• replace the dynamic mega runtime test fixture with Top50 balanced feature-snapshot coverage
