Add possibility to extract something from codebase indexing. Like node_modules.

Cursor look like exclude it by default but also not configurable. Also i am not sure but it look like hidden files indexed also. Have no idea how to check. It very bad cause can contains passwords.

Not sure if it solves your issue but I need separate .kilocodeignore and .kilocodeindexignore to optimize indexing while allowing KC access some unindexed files (tests debug/output files), like Cursor has its.
