fix(#155): stop forcing OutputRendering=Ansi, add strikethrough rendering

Your Name · Your Name · commit 4413deb5da58 · 2026-03-25T18:27:16.000+05:30
Issue #155: psmux was forcing $PSStyle.OutputRendering = 'Ansi' during PowerShell init, overriding the default 'Host' mode. This was a leftover from early development (commit 2c53984) when it was incorrectly believed to be needed for ConPTY. ConPTY correctly presents as a console host, so PowerShell's Host mode auto-detects ANSI capability without help. Removed the forced OutputRendering from all three PSReadLine init constants (PSRL_FIX, PSRL_CRASH_GUARD, PSRL_PRED_RESTORE). The actual crash guard for issue #109 only needs PredictionSource manipulation, not OutputRendering. Also fixed strikethrough (SGR 9) not rendering: the vt100-psmux parser already handled the attribute internally, but Cell lacked a strikethrough() accessor and rendering.rs never mapped it to Modifier::CROSSED_OUT.
