mios.toml [terminal]: edge-to-edge framing (frame_width=79, right_margin=1)

Operator 2026-05-09: "ALL dashboards render to the edge of the
MiOS app window size constraints!!".

Was: frame_width=75, right_margin=5
     -- 5 cells of right-side gap in an 80-col window; dashboard
        looked floaty inside the WT viewport.

Now: frame_width=79, right_margin=1
     -- rightmost `│` border lands at col 78 leaving 1 cell of
        safety against WT's pseudo-console over-reporting
        WindowWidth by 1 cell during the first paint (before
        scrollbarState='hidden' applies).  Effectively edge-to-edge
        in WT 1.18+ with launchMode=focus + scrollbarState=hidden
        + padding=0 (the MiOS profile defaults).

The legacy 5-cell margin was empirically derived during a
period when WT's pseudo-console + acrylic blur + sub-pixel
rounding compounded; modern WT reports the visible cell count
correctly from FIRST paint.  Bump back to 5 ONLY if powerline
wrap returns (operator-tunable in mios.html).

Get-MiosFrameWidth (build-mios.ps1) and Show-MiosDashboard /
mios-dashboard.sh all read these two keys, so the change
propagates to every framed surface in one edit.

-frame_width         = 75      # = cols - 5. Diagnostic root cause of the 5-hour wrap loop: Write-Host CRLF auto-wrap, NOT chrome reservation alone. When Write-Host emits a string EQUAL to display width N, cursor hits col N (phantom rightmost), auto-wraps to col 0 of next line, then CRLF advances one MORE line -- producing the orphan `|` row between every content row in operator screenshots at 18:38 / 20:26 / 20:38. The 20:48 screenshot at margin=4 / frame=76 stopped the orphan rows BUT the right `│` border landed exactly on the visible edge (col 75 in display=76) and was invisible/clipped. Bumping to margin=5 / frame=75 puts the right `│` at col 74 with 1 visible cell of clear slack to the right edge. Install-MiOSPowerShellProfile writes [Console]::WindowWidth to M:\MiOS\diagnostics\window-width.txt at profile load so the actual cell count is recorded -- if WindowWidth != 80, recompute right_margin = cols - WindowWidth + 2.
