- TOC: add Go under Analysis Backends
- Mermaid diagram: add cldk.analysis.go → codeanalyzer-go branch and Go models node
- Update "full support for Java, Python, C" → include Go
- Update cldk.models example list to include cldk.models.go
- Add Go backend section: tools, capabilities, prerequisites, usage snippet

Merges origin/main (40 commits) and adapts the Go language support to the
refactored per-language factory pattern introduced on main.

Conflict resolutions:
- pyproject.toml: bump codeanalyzer-java/python/typescript to main versions;
  retain codeanalyzer-go = 0.1.0 in [tool.backend-versions]
- README.md: adopt main's cleaner structure; add Go row to supported-languages
  table, Go node to architecture Mermaid diagram, CLDK.go() in Quick Start
- cldk/core.py: keep main's per-language factory layout; add CLDK.go() factory
  and wire Go into the deprecated analysis() shim via GoCodeAnalyzerConfig
- uv.lock: regenerated from resolved pyproject.toml

API conformance (Go):
- backend_config.py: add GoCodeAnalyzerConfig dataclass, GoBackend union, and
  "go" key in _CACHE_KEYS so cache_subdir computes the right output path
- GoAnalysis.__init__: replace (analysis_backend_path, analysis_json_path,
  cache_dir) with backend: GoBackend | None = None; derive output path via
  cache_subdir(backend.cache_dir, project_dir, "go")
- GoCodeanalyzer.__init__: drop analysis_backend_path (always PATH) and
  cache_dir (folded into analysis_json_path); clean up unused imports
- core.py: add CLDK.go() static factory; update analysis() Go branch to call
  CLDK.go() with GoCodeAnalyzerConfig
- Tests: update GoAnalysis instantiations to use new backend= API

…sis=True

Previously GoCodeanalyzer bypassed its own analysis.json cache when
eager_analysis=True, but never forwarded --eager to the binary. The
binary's own internal cache (~/.cldk/go-cache) was therefore still used,
so repeated eager calls could return stale results.

Pass --eager to the subprocess args unconditionally when eager_analysis
is set; the binary will force a clean rebuild and ignore its cache.

Tests: add test_eager_flag_passed_to_binary and
test_eager_flag_absent_when_not_eager in test_go_analysis.py, patching
subprocess.run at the GoCodeanalyzer layer to assert on the argv.

…→ binary

CLDK.go() accepted target_files but neither passed it to GoAnalysis nor did
GoAnalysis or GoCodeanalyzer forward it to the codeanalyzer-go binary. The
--target-files flag therefore had no effect, silently ignoring incremental
mode.

Changes:
- GoCodeanalyzer.__init__: add target_files: Optional[List[str]] = None;
  append one --target-files <path> per entry in _run_and_parse
- GoAnalysis.__init__: add target_files param; forward to GoCodeanalyzer
- CLDK.go(): add target_files param; forward to GoAnalysis
- analysis() shim: forward target_files to CLDK.go()

Tests: add test_target_files_passed_to_binary and
test_target_files_absent_when_none in test_go_analysis.py.

Java, Python, and TypeScript all define an abstract base class that
every analysis backend implements, letting GoAnalysis hold its backend
via the interface rather than the concrete type. This commit brings Go
to parity:

- Add cldk/analysis/go/backend.py with GoAnalysisBackend(ABC) exposing
  six abstract methods: get_application, get_symbol_table, get_all_files,
  get_file, get_all_types, get_all_callables.
- Make GoCodeanalyzer subclass GoAnalysisBackend (satisfies ABC at class
  definition time; TypeError at startup if any abstract method is missing).
- Type GoAnalysis._codeanalyzer as GoAnalysisBackend so static type
  checkers enforce the interface boundary.
- Export GoAnalysisBackend from cldk/analysis/go/__init__.py.
- Add two unit tests: GoCodeanalyzer is a subclass of GoAnalysisBackend
  (issubclass), and GoAnalysis._codeanalyzer is a GoAnalysisBackend
  instance at runtime (subprocess-stub pattern, no mock needed).
- Fix test_e2e_application_round_trips_pydantic: cache_subdir writes
  analysis.json under <cache_dir>/go/, not directly under cache_dir.
