* chore: remove 'incubating' branding, update docs & packaging
Replace references to 'incubator'/'incubating' across the repo to the final 'hugegraph' branding and packaging names. Updates include: removal of DISCLAIMER, NOTICE year bump, README and docs link/badge fixes, pom final.name changes (remove -incubating suffix),
Dockerfile and assembly scripts adjusted to new package paths, numerous docs and tests updated to new URLs/paths, mailing list/contact updates, and minor serena project.yml additions.
