Description

Fix the malformed dependency adjustment reported in #286. The generated dependency rules now append : only to non-empty dependency entries, so Android rebuilds no longer require stale .d files to be removed manually.

The required build number, changelog, and source-build documentation were updated as part of the same fix.

Type of change

• Fixes rules_base contains malformed adjustment #286
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

Ran the exact sed pipeline against a representative generated dependency block containing a target, continued header dependency, comment, and blank line. The output contained only:

src/foo.cpp :
include/foo.h :

Also ran git diff --check successfully.

Test Configuration:

• Hardware: Windows 11 x64
• Test steps: Git Bash 5.2.37, GNU sed pipeline regression fixture

Thank you for your contribution.
The described issue turned out to be a red herring and can be solved in another way.
