chore(deps): bump polars 0.52 -> 0.53 + adopt new DataFrame::new signature#479
Merged
Conversation
polars 0.53 changes `DataFrame::new(Vec<Column>)` to `DataFrame::new(usize, Vec<Column>)`. The first argument is the declared row count (`height`) so empty inputs still construct typed zero-row frames. Pass the existing `n = self.len()` binding from the template; regen `frames_generated.rs`. Tested locally with `cargo test -p thetadatadx --features polars --test test_frames_polars` (9 passing).

* chore(release): 8.0.27 - polars 0.52 -> 0.53 (#479) - conditions code 61 scrubbed to PRICEVOLUMEADJ (#480) * chore(release): refresh sub-Cargo.lock files for 8.0.27 The workspace bump only updated the root Cargo.lock; tools/mcp, tools/server, sdks/python, sdks/typescript carry their own lockfiles that pin thetadatadx by version. CI's --locked check failed because they still pinned 8.0.26.

What
Bump polars 0.52.0 -> 0.53.0 and migrate generated frame code to the new
DataFrame::new(height, Vec<Column>)signature.Supersedes #464 (dependabot's bare bump alone fails to compile because polars 0.53 changed the signature).
Why
polars 0.53 reshapes the public
DataFrame::newconstructor from(Vec<Column>) -> PolarsResult<Self>to(usize, Vec<Column>) -> PolarsResult<Self>, where the newusizeargument is the declared row count. The old signature is gone, so the bare bump produced 16 compile errors incrates/thetadatadx/src/frames_generated.rs.How
