chore(deps): Bump ty from 0.0.84 to 0.0.86

[dependabot]

Bumps ty from 0.0.84 to 0.0.86.

Release notes

Sourced from ty's releases.

0.0.86

Release Notes

Released on 2026-10-09.

The executables in our macOS and Windows release archives and ty wheels are now code-signed. macOS executables are signed with an Apple Developer ID certificate and notarized by Apple. Windows executables have timestamped Authenticode signatures from Azure Artifact Signing. This enables verification of the release publisher and binary integrity, supports publisher-based allowlisting, and should reduce security warnings and antivirus false positives.

Bug fixes

• Infer empty collection branches from nonempty literals (#29131)
• Invalidate dependency metadata when environments change (#29126)
• Preserve final attribute restrictions on composite types (#29135)
• Preserve recursive structure in Annotated values (#29058)
• Specialize inherited dataclass field converters (#29192)

LSP server

• Show documentation for annotation operators on hover (#29185)

Core type checking

• Check attribute and property override types (#28556)
• Narrow tuple unions through truthiness and type checks (#29125)
• Preserve literal types when consuming dictionary literals (#29145)
• Preserve non-boolean comparison results for intersections (#28045)
• Preserve receiver specializations when calling unions of bound methods (#29015)
• Represent uninhabited truthiness explicitly (#28843)
• Solve validity type context through constraint sets (#28909)

Performance

• Avoid recursion guards for non-generic nominal targets (#29202)
• Check exact exclusions before intersection positives (#29195)

Memory usage improvements

• Share constraints in retained sequent maps (#28966)

Other changes

• Update the default Python version to 3.15 (#28792)
• Update to Unicode 17 (#21229, #28784)
• Always show fixes in the CLI (#27810)
