Update dependency analysis artifacts

Refreshed static analysis of workspace dependency structure:
- graph.json: 10 crates, 17 crate-level edges, 95 files, 123 file-level edges
- graph.summary.md: Updated metrics and fan-in/fan-out rankings
- sccs.md: Confirmed no cycles (DAG structure intact)
- layers.observed.md: 5-layer hierarchy from binaries to infrastructure
- hotspots.md: Identified g3-config, g3-providers as high fan-in; g3-cli as high fan-out
- limitations.md: Documented extraction method constraints

-## Extraction Method
+## Extraction Limitations
 
-- Crate dependencies: Parsed from `Cargo.toml` files
-- File-to-crate edges: Extracted from `use g3_*::` statements
-- Module declarations: Extracted from `mod` and `pub mod` statements
-- File classification: Based on path patterns and filename conventions
+- Only `use` and `mod` statements at line start are parsed
+- Conditional compilation (`#[cfg(...)]`) not evaluated
+- Macro-generated imports not detected
+- Re-exports through `pub use` not fully traced
+- Test modules (`mod tests`) excluded from graph
+- Test files (`*_test.rs`, `tests/`) excluded from graph
