read_file ignores offset/limit arguments and returns the whole file (v0.2.46, DXT on Windows) #686

Title: read_file ignores offset/limit arguments and returns the whole file (v0.2.46, DXT on Windows)

Body:

Environment: Desktop Commander 0.2.46 installed as DXT inside Claude Desktop (client reports local-agent-mode-Desktop Commander 1.0.0), Windows 11 x64, Node 24.18.1 (Electron 42.10.0). fileReadLineLimit is the default 1000.

Steps to reproduce:

1. Call read_file with path pointing to a UTF-8 markdown file of ~130 lines and limit: 3 (also tried with offset: 0, limit: 3).
2. Observe the response.

Expected: 3 lines (per the tool description: "Read the file in chunks using offset and limit").

Actual: the whole file is returned (130 and 134 lines in two cases). For a 1002-line file the response was cut at 1000 lines, i.e. pagination appears to follow fileReadLineLimit only and the per-call limit is not applied. Reproduced three times in one session on three different files. Reading the same line range with a small Python script returns the expected 3 lines, so the files themselves are fine.

Impact: every read_file on a large file fills the model context with the full file, defeating the purpose of offset/limit.

Happy to provide the exact request/response JSON if useful (files are private, but I can reproduce on a synthetic file).
