Add category-based fetch script, fix .gitignore for vendor source

Add local/scripts/fetch-sources.sh for fetching sources by category (core, libs, tools) instead of by config. Fix .gitignore to only track our hand-written source code (branding, core, drivers, gpu, system, wayland, kde categories), excluding fetched vendor source like MC's ported source tree.

+# The build system fetches on-demand during `make all`, but you need sources
+# present BEFORE building to read, edit, and patch them. This script bulk-fetches
+# sources so they're available in recipes/<category>/<pkg>/source/.
+#
+# Usage:
+#   ./local/scripts/fetch-sources.sh                # All sources
+#   ./local/scripts/fetch-sources.sh core           # Core packages only
+#   ./local/scripts/fetch-sources.sh libs tools     # Multiple categories
+#   ./local/scripts/fetch-sources.sh --list         # Show available categories
+#   ./local/scripts/fetch-sources.sh --status       # Show fetch progress
+#
+# After fetching, sources live at:
+#   recipes/<category>/<pkg>/source/       (git repos, tar extractions)
+#   local/recipes/<category>/<pkg>/source/ (our custom overlay packages)
