rust-analyzer's call hierarchy is function-only, so a type root is walked
via find-references instead: each mention is attributed to its enclosing
document symbol (function, type definition, or impl block's self type),
and a type's callees are its methods. Type nodes are square; new edge
kinds `ref` and `member` get their own labels and legend entries.

* Add tools/callgraph: interactive call-graph reports via rust-analyzer
Generates a self-contained HTML report for one function: pan/zoom graphviz
graph of callers and callees, per-node docs and source snippets, exact call
sites with context, GitHub/editor links.
- rust-analyzer call hierarchy over LSP gives resolved (not textual) edges;
trait declarations and impls are bridged via goto-declaration /
goto-implementation so dispatch through a trait doesn't dead-end the walk
- test code excluded by running rust-analyzer with cfg(test) disabled, plus
path filters for tests/, benches/, examples/ targets
- no dependencies beyond rust-analyzer and graphviz on PATH
