feat: add overlay to remove connector-specific models from generated SDK

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

Summary

Adds a Speakeasy overlay that replaces the SourceConfiguration, DestinationConfiguration, and OAuthCredentialsConfiguration oneOf unions with generic object schemas requiring sourceType/destinationType discriminator fields. After regeneration, this eliminates ~600 connector-specific Python model files and ~1,800 doc files (~126K lines / ~14MB).

Verified result: Generation succeeded and all CI checks pass. The diff is 2705 files changed, 273 insertions(+), 126,086 deletions(-). Zero source/destination connector model files remain; 96 core model files are retained.

What the overlay does (4 remove + 4 update actions):

1. Removes the oneOf arrays from SourceConfiguration, DestinationConfiguration, OAuthCredentialsConfiguration
2. Removes the enum array from OAuthActorNames
3. Replaces each with a generic typed schema:
   • SourceConfiguration → {type: object, required: [sourceType], additionalProperties: true}
   • DestinationConfiguration → {type: object, required: [destinationType], additionalProperties: true}
   • OAuthCredentialsConfiguration → {type: object, additionalProperties: true}
   • OAuthActorNames → {type: string} (forward-compatible)

Usage change:

# Before: must import specific connector model
from airbyte_api.models import SourcePostgres
config = SourcePostgres(host="localhost", port=5432, sourceType="postgres", ...)

# After: pass a plain dict with required discriminator
config = {"sourceType": "postgres", "host": "localhost", "port": 5432, ...}

Breaking change: Typed connector model imports (SourcePostgres, DestinationBigquery, etc.) no longer exist. Should accompany a major version bump.

Pull request overview

This PR introduces a Speakeasy overlay (and enables it in the Speakeasy workflow) intended to dramatically reduce SDK bloat by replacing connector-specific oneOf unions for connector configurations with generic object schemas that require discriminator fields (sourceType / destinationType).

Changes:

• Add overlay actions to replace SourceConfiguration / DestinationConfiguration oneOf unions with generic object schemas requiring discriminator fields.
• Replace OAuthActorNames from a closed enum to a plain string for forward compatibility.
• Enable the overlay in .speakeasy/workflow.yaml so it is applied during generation.

Aaron ("AJ") Steers (@aaronsteers) Done — merged main, resolved conflicts (overlay now includes both the connector model removal actions and the RowFilteringOperationNot circular-ref fix from main), and re-triggered /generate to regenerate the SDK. Waiting for the generation workflow to push updated code.
