feat: document upgrade stacking behaviour as multiplicative (#75)

## Summary - Adds a `💡` stacking note directly in the upgrade panel below the progress counter so players see it without visiting the About page - Updates the About panel's Upgrades how-to-play entry to replace the vague "compound with each other" with explicit multiplicative stacking language, including an example (two ×2 upgrades = ×4) and a note that global upgrades multiply on top of adventurer-specific ones ## Test plan - [ ] Verify the stacking note appears in the upgrade panel below the progress counter - [ ] Verify the About panel Upgrades entry reflects the updated wording - [ ] Confirm lint, build, and tests all pass Closes #60 Reviewed-on: #75 Co-authored-by: Hikari <hikari@nhcarrigan.com> Co-committed-by: Hikari <hikari@nhcarrigan.com>
