  1. feat(bash): index shell scripts (functions, call edges, source imports) 

    Shell was the biggest remaining gap for infrastructure repos: a hooks or
scripts tree is dozens of small files wired together by `source`, and none
of it was visible to the graph. Closes #239.

Wiring is the usual four files plus one branch in extractCall. Two choices
are worth calling out:

- The grammar is VENDORED. tree-sitter-wasms ships an ABI-14 bash build
  that traps under web-tree-sitter 0.25 the moment it meets a `case`
  statement ("resolved is not a function", taking the whole parse with it),
  so it dies on nearly every real script. The prebuilt ABI-15 wasm from the
  tree-sitter-bash 0.25.1 npm package parses the same files cleanly; this is
  the same class of problem as the vendored Lua and C# grammars.

- Builtins are filtered out of call edges. Every `command` node is a call
  site, so without a filter `echo`/`printf`/`local` outnumber real function
  calls by roughly an order of magnitude and bury them. External tools
  (`git`, `jq`) are deliberately kept as unresolved references, since that
  is what makes "which scripts shell out to jq" answerable.

Measured on a 339-file hooks/scripts tree: 10,339 nodes and 19,772 edges in
about 0.5s, 1,466 functions, 276 resolved `source` dependencies, and
cross-file `callers`/`impact` working through them (one library function
returned 20 callers across 20 different hook files, 147 affected symbols).
