* M2: heavy-sheet generator and page timing harness (item 8 of storytold/pdfcraft#623)
Adds two examples to pdfcraft-render. synth_sheet writes a synthetic A1 sheet whose content
follows the sample's layout, so timings on it can be compared with the sample. page_timing
replays the canvas's requests for page 1 and prints times, counts and an output hash. The
renderer is unchanged. Budgets are reported, not enforced.

* M2: sort sweep results by tile size too (item 8 of storytold/pdfcraft#623)
Tiles at the same origin but different sizes compared equal under the sort key, so the
sweep hash depended on completion order. Including the size makes the key unique.
