0; update the computation around the expression that assigns reduction (the line
using Math.round((1 - totalStripped / totalOriginal) * 100)) to guard against
totalOriginal === 0 and produce a sensible default (e.g., 0) instead of
performing the division — replace the direct expression with a conditional that
checks totalOriginal and only computes the percentage when nonzero, otherwise
sets reduction to 0.

Guard against division by zero for empty files.
If a markdown file is empty, originalSize will be 0, causing reduction to be NaN (or Infinity if strippedSize is also 0).

Same division-by-zero edge case in summary calculation.
If no files are processed (empty docs directories), totalOriginal would be 0.
Proposed fix
- const reduction = Math.round((1 - totalStripped / totalOriginal) * 100)
+ const reduction = totalOriginal > 0

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Move @tanstack/llm-docs to devDependencies.
The @tanstack/llm-docs package is not used in any runtime code and should not be a production dependency. This unnecessarily increases bundle size for all consumers of @tanstack/router-core.
