DEP(deps): Update cachetools requirement from ~=6.2.6 to ~=7.0.2

[dependabot]

Updates the requirements on cachetools to permit the latest version.

Changelog

Sourced from cachetools's changelog.

v7.0.2 (2026-03-02)

• Provide more efficient clear() implementation for all support Cache classes (courtesy Josep Pon Farreny).

v7.0.1 (2026-02-10)

• Various test improvements.

• Update Copilot Instructions.

v7.0.0 (2026-02-01)

• Require Python 3.10 or later (breaking change).

• Drop support for passing info as fourth positional parameter to @cached (breaking change).

• Drop support for cache(self) returning None with @cachedmethod (breaking change).

• Convert the @cachedmethod wrappers to descriptors, deprecating its use with class methods and instances that do not provide a mutable __dict__ attribute (potentially breaking change).

• Convert the previously undocumented @cachedmethod attributes (cache, cache_lock, etc.) to properties for instance methods, providing official support and documentation (potentially breaking change).

• Add an optional info parameter to the @cachedmethod decorator for reporting per-instance cache statistics. Note that this requires the instance's __dict__ attribute to be a mutable mapping.

v6.2.6 (2026-01-27)

• Improve typedkey performance.

• Minor documentation improvements.

• Minor testing improvements.
