[ENHANCEMENT] Allow line-range reads when "Always read entire file" is enabled

Enhancement

Problem / Value

When "Always read entire file" is enabled, you can’t request just specific lines. This slows down targeted work (and adds noise) when people are acting on outputs that reference line numbers. Allowing line-range reads would make focused edits and navigation faster and clearer.

Context

Affects users working from:

• Diffs or patches that reference lines
• Search results like git grep -n
• Tool outputs (linters, compilers, blame, logs) that include line numbers

This commonly occurs during code review, bug fixing, and refactors. Modern models handle multiple targeted reads well, so enabling explicit line-range reads helps them stay precise without overloading context.

Constraints/Preferences (optional)

• Keep default behavior unchanged when no range is provided
• Allow explicit line-range reads even if "Always read entire file" is on
• Minimize redundant re-reads and unnecessary context to stay efficient

I'm exploring a potential fix for this enhancement to allow line-range reads when 'Always read entire file' is enabled. I'll open a PR to share progress.
