Pull Request Overview
This PR refactors the handling of quantized data vectors by splitting them into two tapes: one immutable (frozen) and one appendable. Key changes include updates to tape writer construction and usage in multiple modules, removal of the Pipe trait, and renaming of functions and types to reflect the new split-tape design.

- The loop condition 'while pages.is_empty()' may be incorrect because it will execute only when 'pages' is empty. If the intent is to process provided pages, consider changing the condition to 'while !pages.is_empty()'.
while pages.is_empty() {
crates/algorithm/src/build.rs:56
- [nitpick] Verify that the new field name 'frozen_first' clearly indicates that it represents the starting pointer of the immutable tape. If necessary, consider adding comments or renaming related fields to differentiate it from the appendable tape pointer.
