v2.16.6 — ctx_edit CRLF fix for Windows

on GitHub

ctx_edit: Windows CRLF support

ctx_edit failed on Windows because files use \r\n (CRLF) but agents send old_string with \n (LF). The exact string match failed silently, causing fallback to Write (full-file rewrite) or Bash.

Fixed

• CRLF/LF auto-normalization — ctx_edit detects the file's line ending style and converts old_string/new_string to match. CRLF ↔ LF works transparently in both directions.
• Trailing whitespace tolerance — If exact match fails, ctx_edit retries after trimming trailing whitespace per line, matching the original span.
• Better error messages — Failed matches on CRLF files now show "(file uses CRLF line endings)".
• 9 unit tests covering CRLF→LF, LF→CRLF, trailing whitespace, and combined scenarios.

Also in v2.16.5 (same session)

• ctx_edit MCP tool — Search-and-replace without native Read/Edit dependency.
• Instructions v7 — Anti-loop guidance: "NEVER loop on Edit failures — use ctx_edit."
• PREFER over NEVER — Native tools allowed as fallback.
