chore(release): 8.0.27 (#483)

* 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.

+- **polars 0.52 -> 0.53.** Adopts the new
+  `DataFrame::new(height: usize, columns: Vec<Column>)` signature in
+  `crates/thetadatadx/build_support/ticks/rust_frames.rs` (the existing
+  `n = self.len()` binding feeds the new `height` argument). Re-runs of
+  `generate_sdk_surfaces` produce `frames_generated.rs` with the
+  updated call form. Closes #464.
+
+### Fixed
+
+- **`crates/tdbe/src/conditions.rs` trade condition 61 renamed from
+  a third-party product mark to `PRICEVOLUMEADJ`.** Same scrub pattern
+  as the v8.0.26 exchange-code-0 rename. Single tracked-source
+  occurrence; `rg 'NANEX'` now clean. Description unchanged. Closes
+  #476's sibling, filed as #480.
