Standardize naming convention so all Ehlers-originated indicators have "Ehlers" in their display name across all documentation and code surfaces: - SAM: Smoothed Adaptive Momentum → Ehlers Smoothed Adaptive Momentum - PMA: Predictive Moving Average → Ehlers Predictive Moving Average - ILRS: Integral of LinReg Slope → Ehlers Integral of LinReg Slope - CTI: Correlation Trend Indicator → Ehlers Correlation Trend Indicator - RVGI: Relative Vigor Index → Ehlers Relative Vigor Index Updated across: .md H1 titles, XML doc summaries, Quantower Name properties, Quantower test assertions, _sidebar.md, lib/_index.md, category _index.md files, docs/indicators.md, docs/validation.md. Build: 0 warnings, 0 errors. All tests pass.
