…se class refactoring
- Add separate checksums for source and test inputs for enhanced build incrementality
- Implement web-path compatible cache key format: `{source_checksum}-{test_checksum}`
- Increment cache version to v1.2 (breaking change)
- Create AbstractInputAnalyzer base class to eliminate code duplication
- Refactor SrcInputAnalyzer and TestInputAnalyzer to extend base class
- Reduce code duplication by ~300 lines (60% reduction)
- Add comprehensive tests for dual checksum functionality
Enhanced build logic:
- Source-only changes: rebuild only if source checksum differs
- Test-only changes: rebuild only if test checksum differs OR source changes
- Both changed: full rebuild required
- Neither changed: use cached results

getBytes() is using the platform's default charset, for portability between win/linux it is better to set encoding.

this will recalculate again sourceChecksum and testChecksum - could be calculated once
| DigestItem fileDigest = DigestUtils.file(checksum, baseDirPath, file); | ||
| items.add(fileDigest); | ||
| if (compareWithBaseline) { | ||
| sourcesMatched &= checkItemMatchesBaseline(baselineHolder.get(), fileDigest); |

that was a diff report (compare 2 buildinfos from different sources to find mismatches). is it moved or deprecated?

it should be FULL_REBUILD - please remove && testChanged
