Large TypeScript files silently produce zero Function/Module nodes #213

Description

Large TypeScript files are indexed (a File node is created) but tree-sitter parsing silently fails — no Module, Function, Method, Variable, or Interface nodes are produced. No error is reported to the user.

Reproduction

Indexing a TypeScript/Deno project with these files:

Files of similar or larger size in the same project DO index successfully:

Impact

The 3 most critical business logic files (containing the core trading algorithm, trade execution pipeline, and health monitoring) are completely invisible to search_graph, trace_call_path, and get_code_snippet. Call graph analysis stops at these file boundaries.

Environment

• Version: 0.5.7
• OS: Linux 6.8.0-107-generic
• Language: TypeScript/Deno

Suspected Cause

The binary contains the string userconfig.file_too_large and Expression tree is too large (maximum depth %d), suggesting an internal limit based on AST complexity rather than raw file size. The failure appears to be in the parse phase — the file walker creates the File node but tree-sitter parsing never completes.

Related issues: #130 (quadratic ts_node_child loop on large ASTs), #62 (stack overflow on large files)

Expected Behavior

Either: successfully index these files (preferred), or report a clear warning/error that the file was skipped due to size/complexity limits so users know their index is incomplete.
