fix: derive sub-package __version__ from a single source of truth

[KomanRudden]

Makes kinde_sdk/_version.py the source of truth for the SDK version: the top-level package, both generated sub-packages, and pyproject.toml now all derive from it.
Generator scripts read the same value to set packageVersion, and bumps the SDK to 2.3.0.
Adds a regression test that fail if any of those four versions ever go out of sync.

Walkthrough

This PR consolidates Python SDK version management to a single source of truth. It creates kinde_sdk/_version.py containing the canonical __version__ definition, updates all runtime packages to import from it, and modifies both code generators to write dynamically-imported version statements in generated sub-packages instead of embedding literal versions.

Changes

Version consolidation to single source of truth

Layer / File(s)	Summary
Canonical version source kinde_sdk/_version.py	Establishes a minimal module with no external imports defining __version__ = "2.2.0" as the authoritative version for the entire SDK.
Package version imports kinde_sdk/__init__.py, kinde_sdk/management/__init__.py	Both main and management packages now import __version__ from kinde_sdk._version instead of defining it locally, eliminating duplicate version strings.
Frontend generator version sync generate_frontend_sdk.py	Adds _read_sdk_version() to read from the canonical version file, replaces hardcoded 2.0.0 with dynamic SDK_VERSION in config generation, and introduces make_version_dynamic() to rewrite the generated frontend __init__.py to import __version__ instead of embedding a literal.
Management generator version sync generate_management_sdk.py	Adds _read_sdk_version() and make_version_dynamic(), updates OpenAPI configuration and command-line packageVersion properties to use the dynamic SDK_VERSION, and rewrites the generated management __init__.py to import __version__ dynamically for consistency across regenerations.

generate_frontend_sdk.py (1)

241-254: 💤 Low value

Minor: Comment references wrong source file.

Line 243 states packageVersion is derived from kinde_sdk/__init__.py's __version__, but the generator actually reads from kinde_sdk/_version.py directly via _read_sdk_version(). Consider updating the comment for accuracy.

📝 Suggested fix

-# packageVersion is derived from kinde_sdk/__init__.py's __version__.
+# packageVersion is derived from kinde_sdk/_version.py's __version__.

generate_frontend_sdk.py incorrectly states the packageVersion is derived from

(or the _read_sdk_version() helper) and/or say it is derived from SDK_VERSION
