ci: remove hardcoded version from _version.py via post_generate.py

[Aaron ("AJ") Steers (aaronsteers)]

Summary

Follow-up to #175 and #176. Removes the hardcoded __version__ from the Speakeasy-generated _version.py using post_generate.py — a surgical patch that runs after each Speakeasy generation.

Approach: Let Speakeasy generate _version.py normally (keeping __openapi_doc_version__ and __gen_version__ current), then post_generate.py replaces:

-__version__: str = "1.0.0"
+__version__: str = importlib.metadata.version(__title__)

-__user_agent__: str = "speakeasy-sdk/python 1.0.0 2.911.0 1.0.0 airbyte-api"
+__user_agent__: str = (
+    f"speakeasy-sdk/python {__version__} {__gen_version__}"
+    f" {__openapi_doc_version__} {__title__}"
+)

-try:
-    if __package__ is not None:
-        __version__ = importlib.metadata.version(__package__)
-except importlib.metadata.PackageNotFoundError:
-    pass

No silent fallback — importlib.metadata.version() raises PackageNotFoundError if the package isn't installed. At build time, uv-dynamic-versioning writes the git tag version into package metadata.

The script is idempotent — running it on an already-patched file is a no-op. No .genignore needed since generation metadata stays auto-updated by Speakeasy.

Pull request overview

This PR updates the SDK’s runtime version reporting to derive __version__ from installed package metadata (populated by uv-dynamic-versioning from git tags), removing the hardcoded version string previously committed in _version.py.

Changes:

• Resolve __version__ via importlib.metadata.version("airbyte-api") with a fallback when metadata is unavailable.
• Recompute __user_agent__ based on the resolved runtime version and existing Speakeasy metadata constants.
• Add src/airbyte_api/_version.py to .genignore to prevent regeneration from reintroducing a hardcoded version.

.genignore	Excludes _version.py from Speakeasy regeneration to avoid hardcoded version drift.
