feat: rebase Java support onto main

[KRRT7]

Summary

• Rebase of omni-java (PR codeflash-omni-java #1199) onto main, removing JS/Python language branches that main refactored into protocol dispatch
• Keeps all is_java() guards intact — Java-specific code is unchanged
• Work in progress: more files still need branch removal before a clean merge with main

Files aligned so far

• aiservice.py — removed Python/JS language metadata and framework validation branches
• discover_unit_tests.py — removed JS test config branch
• unused_definition_remover.py — removed is_python() guard
• parse_test_output.py — removed JS/Python serialization, coverage, and XML parsing branches

Still remaining

• verification_utils.py, verifier.py, code_context_extractor.py, code_replacer.py
• function_optimizer.py, optimizer.py, test_runner.py
• concolic_testing.py (delete), test_multi_file_code_replacement.py
• config_consts.py, equivalence.py

PR Review Summary

Prek Checks

All checks passed -- ruff check and ruff format passed with no issues.

Mypy

530 mypy errors detected across checked files, but the vast majority are pre-existing (e.g., ~118 from tabulate.py, many from console.py, config_parser.py). No new type errors were introduced by this PR changes. The new Java module files have complex type issues that would require significant refactoring.

Code Review

Critical: NoneType crash in parse_test_output.py:1213
When running Python tests with coverage data, coverage stays None because the CoverageUtils.load_from_sqlite_database path was removed. coverage.log_coverage() will crash with AttributeError. The CoverageUtils import was also removed. Fix: guard with if coverage is not None: or restore the Python coverage path.

Regression: Concolic tests disabled in function_optimizer.py:2100
future_concolic_tests is now always None. The method was moved to PythonSupport.generate_concolic_tests() but is never called. Previously ran via executor for non-subagent mode. Unclear if this is intentional.

Stale comments/dead code in parse_test_output.py

• Line 25: Import Jest-specific parsing comment left after import was removed
• Lines 563, 572, 578: Comments reference Jest/Java but Jest is removed
• Lines 1220-1225: Jest coverage directory cleanup is dead code

Test Coverage

File	main	PR	Delta
codeflash/api/aiservice.py	22%	20%	-2%
codeflash/code_utils/config_consts.py	89%	89%	--
codeflash/discovery/discover_unit_tests.py	74%	76%	+2%
codeflash/languages/python/context/unused_definition_remover.py	94%	94%	--
codeflash/languages/python/support.py	54%	40%	-14%

codeflash/verification/verification_utils.py	62%	56%	-6%
TOTAL	50%	48%	-2%

Notes:

• python/support.py dropped 14% because the moved generate_concolic_tests method (~108 lines) has no test coverage
• verification_utils.py dropped 6% from added Java test framework detection code without tests
• parse_test_output.py improved 5% from removing dead JS code paths
• concolic_testing.py was deleted (existed only on omni-java base, not on main)
• 2 pre-existing test failures unrelated to this PR: test_tracer_initialization_normal, test_mirror_paths_for_worktree_mode
