mudler's LocalAI [bot] 6e52d0c2ef fix(ci): rebuild backends when shared build inputs change (#10975) ...

The backend matrix path filter only matched files under a backend's own
directory, so a change to shared build infrastructure rebuilt nothing at
all: an empty matrix, every job green, and the change reaching no image.

PR #10946 fixed scripts/build/package-gpu-libs.sh shipping a partial
4-of-8 cuDNN library set, which mixed versions with the venv's pip cuDNN
and produced CUDNN_STATUS_SUBLIBRARY_VERSION_MISMATCH at inference time.
It merged 1h48m after the weekly full-matrix cron had already run, so no
backend image ever received the fix and nothing signalled that it had
been un-shipped.

Add a SHARED_BUILD_INPUTS table mapping each shared path to the narrowest
set of matrix entries it can honestly invalidate, plus a generic rule for
backend/Dockerfile.<x> (which each entry already names). A full matrix is
417 Linux + 56 Darwin builds, so package-gpu-libs.sh now rebuilds the 176
Python entries rather than everything. Unclassified files under
scripts/build/ fall back to a full rebuild deliberately: over-building is
recoverable, silently shipping nothing is not.

Extract the filtering logic to scripts/lib/backend-filter.mjs so it can be
unit-tested without bun, js-yaml or a GitHub API round-trip, and run those
tests from the existing lint workflow via `make test-ci-scripts`.
