Transcodes echo/log audit pass

ramdisk_setup.sh: path/size detail lines → log (already in log block above);
status done → echo. transcode_cleanup.sh: flip-back decision line and status
done → echo. transcode_manager.sh: clean-run single-line summary → echo.
Manual-Transcoding.md: added Output Tiers section.

+## Output Tiers
+
+All three scripts follow a two-tier output model: `echo` lines are always visible;
+`log` lines only appear when `--log` is passed.
+
+**ramdisk_setup.sh** — one-shot at array start. Without `--log`, section headers
+and the final summary are visible. Per-step creation detail suppressed.
+
+**transcode_manager.sh** — runs every 3 minutes. Without `--log`, only state
+transitions (flips, warnings, errors) and active session display are shown. When
+nothing changes, a single one-line confirmation is printed. Per-check detail suppressed.
+
+**transcode_cleanup.sh** — runs every 3 minutes. Without `--log`, the cleanup
+summary (files removed, space freed) is always visible. Per-file deletion detail
+suppressed.
