Graphenium v0.8.0: Diagnostics, init, auto-watch, transitive direction

Graphenium v0.8.0

Diagnostics, workspace init, auto-watch, and directional transitive queries.

Added

• gm doctor --json — Structured JSON diagnostics with binary, graph, quality, and API key status
• gm init — Workspace initializer: creates .grapheniumignore with sensible defaults (Rust, Python, Node.js toolchains)
• Auto-watch by default — gm serve now automatically watches the graph file for changes and reloads — no more manual reload_graph calls
• query_transitive direction param — Support forward (outgoing edges), reverse (incoming), or both for dependency/impact analysis
• Budget estimation — Truncation messages now estimate remaining characters needed, helping agents calibrate their budget

Fixed

• AST-only policy gates — MinCallResolution policy now auto-passes for AST-only graphs with clear [SKIPPED] message
• is_test_like_path patterns — Added _test.rs and _tests.rs to test exclusion patterns
• Relative paths — analyse_symbol and module_dependencies now use project-root-relative paths
