Update qet_compilation_vars.cmake

The comments describing the terminal_names layout were inherited from a
previous version and no longer matched the actual assignment order:

    terminal_names << nc_name << no_name << common_name;
    i.e. [0]=NC, [1]=NO, [2]=Common

Update all affected comments to reflect the current storage order.

+ * Post-processes a Qt-generated PDF to replace URI link annotations

+ * ([pageObj 0 R /Fit]).  This makes cross-reference links work in all
+ * PDF viewers regardless of where the file is stored.
+ *
+ * The function:
+ *   1. Reads the PDF as raw bytes.
+ *   2. Collects page object numbers in document order by scanning for
+ *      objects that contain "/Type /Page" (but not "/Type /Pages").
+ *   3. Replaces every annotation action block
+ *        /S /URI\n/URI (file://...#page=N)
+ *      with
+ *        /S /GoTo\n/D [<pageObj> 0 R /Fit]
+ *   4. Rebuilds the cross-reference table (offsets change because the
+ *      replacement strings have different lengths).
+ *   5. Writes the result back to the same file.
+ *
+ * The function is intentionally conservative: if any step fails (file
+ * not found, malformed PDF, no URI annotations) it returns silently
+ * without corrupting the file.
