Builds the native image at -O3 instead of -O2 on every platform: native/scripts/build-image.sh passes -Dnative.opt=-O3, the native/pom.xml comment no longer says that -O2 and -O3 are the same on GraalVM CE, and arcadedb._build_info.NATIVE_IMAGE records -O3. The measurements are in #159: the four warm figures have a geometric mean of 0.736, ingest is 11 to 15 percent faster, peak RSS is unchanged, and the library is 1.62x larger.

Verification before merge: pull requests build only linux-x86_64, so I dispatch this workflow on the branch (all four platforms, Python 3.12 and 3.14) and merge when every parity leg passes. The resulting wheel sizes go into a comment here; the project policy is under 100 MB per wheel (scripts/verify_wheel_size.py).

Closes #159

The dispatched run on this branch (41228183408, head 71c31046c6, all four platforms, Python 3.12 and 3.14) passed every leg. Wheel sizes from the native-wheel-* artifacts of that run against the last -O2 run (#156's dispatch):

platform	-O2 (run 41179658884)	-O3 (run 41228183408)	ratio
linux-aarch64	37.7 MB	63.9 MB	1.69
linux-x86_64	37.5 MB	62.7 MB	1.67
macos-arm64	38.1 MB	64.5 MB	1.69
windows-x64	38.2 MB	63.6 MB	1.66

The largest is 64.5 MB, under the 100 MB per-wheel policy. The 1.66 to 1.69x growth on every platform is in line with the 1.62x library growth measured in #159, so -O3 took effect on all four builds.
