[ANE] Add Bazel strategy for MODULE.bazel and maven_install.json#1655
Conversation
Add support for Bazel's modern Bzlmod dependency management system. This parses MODULE.bazel files for bazel_dep() entries and maven extension artifacts, maven_install.json lockfiles for transitive Maven dependencies, and optionally runs `bazel mod graph` for full resolved module graphs. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add strategy documentation at docs/references/strategies/languages/bazel/. Add BazelModGraphSpec tests for `bazel mod graph` JSON parsing. Improve MavenInstallSpec with GraphUtil edge/direct assertions, v1 fallback tests, and coordinate format edge cases (jar, classifier). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The parser was failing on real projects (rules_jvm_external, rules_oci) due to Starlark features it couldn't skip past: bare string docstrings, list comprehensions, .format()/.replace() method chains, string concatenation with +/%, parenthesized expressions, and function calls used as values (e.g. use_repo_rule(...)). Also fixed otherStatement consuming subsequent top-level statements via a greedy skip loop. Tested against rules_oci (13 deps), bazel-examples (5 deps), and rules_jvm_external (16 bazel + 11 maven deps from maven_install.json). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Adds Bazel project support to fossa-cli, focused on the modern Bzlmod system (MODULE.bazel). Bazel 9 removed WORKSPACE entirely, making MODULE.bazel the only dependency management approach.
