Add source code analysis via tree-sitter (v0.3.0)

- vajra-source: parses source code from 9 languages (Rust, Python, Go,
  JavaScript, TypeScript, Java, C, C++, Ruby) into Vajra Documents via
  tree-sitter CST-to-JSON conversion. Auto-detects language from file
  extension. Feature-gated grammars for minimal binary size.

- vajra-domain-source: plugin with 6 type recognizers (snake_case,
  camelCase, PascalCase, SCREAMING_SNAKE, import paths, source file
  paths) and 6 relationship hints for code structures.

- CLI: source code is a first-class input format. `vajra inspect main.rs`
  works. All existing commands (stats, essence, anomalies, fingerprint,
  drift) work on code with zero changes.

- Tests: 13 unit + 9 property suites (10K cases) + 23 chaos tests for
  vajra-source; 30 unit + 6 property suites for vajra-domain-source.
  Chaos covers empty input, malformed code, deep nesting, wide params,
  unicode, null bytes, cross-language, config edges.

- Corpus: 4 source fixtures (Rust, Python, Go, JavaScript) in
  corpus/source/ for golden test integration.

- Docs: updated mdbook (formats, architecture, plugins, testing),
  README, CLAUDE.md, prd.md.

990 tests, 0 failures, 0 clippy warnings, 16 crates.

 Dependencies flow downward. `vajra-core` and `vajra-types` depend on nothing internal. `vajra-cli` depends on everything.
