feat: add the Sync HTTP client foundation

[estivate]

Summary by CodeRabbit

• New Features

  • Added a synchronous HTTP client for configuration management, plan, verify, apply, sync, artifact, validation, cancellation, and run-monitoring workflows.
  • Added typed request and response models with structured, secret-safe error handling.
  • Added compatibility checks, environment-based setup, timeout-aware polling, and artifact integrity validation.
  • Added manual triggering support for the pull request workflow.

• Documentation

  • Updated the Python API reference to document the HTTP client and supported operations.

Replace the embedded Python API with a synchronous HTTP client over the Sync service. External integrations—and the next CLI conversion unit—can now use one typed, compatibility-checked service contract without installing server runtimes.

Key Changes

• Add SyncClient coverage for every shipped Sync API route.
• Provide stable error mapping, compatibility checks, redirect refusal, digest verification, and bounded run polling.
• Move public wire models into a neutral client contract and project server records into them.
• Remove the embedded infrahub_sync.api.v1 façade and obsolete equivalence tests.
• Keep HTTPX in the base package while FastAPI, Prefect, PostgreSQL, and S3 dependencies remain optional.
• Add manual workflow dispatch for reliable CI evidence on stacked PRs.

Related Context

This is unit 1 of the accepted V3 HTTP client conversion and targets feature/v3-develop. CLI conversion and product naming reconciliation remain separate stacked units.

Documentation Updates

• Rewrite the Python API reference around SyncClient.
• Document authentication, compatibility, error handling, run waiting, and artifact verification.

Test Plan

• uv run invoke format
• uv run invoke lint
• uv run ty check .
• uv run pytest -q — 3028 passed, 23 skipped, 1 xfailed
• uv run invoke docs.generate
• uv run invoke docs.docusaurus
• Base-only client import and CLI help verification

Walkthrough

The change replaces the local version 1 Python API with a typed synchronous HTTP client. It adds validated request and resource models, compatibility negotiation, configuration and run operations, artifact verification, polling, and structured errors. Managed routes now return typed resources and project stored runs into standalone wire models. Documentation and dependency declarations reflect the HTTP client. Tests cover client behavior, resource projections, public-surface changes, and manual workflow dispatch.

Merge Risk: 🟡 Moderate · up to c77ea

The new client sends bearer credentials to any configured HTTP(S) service URL, so an untrusted or misconfigured destination could expose credentials and authorized service access; the added manual workflow also inherits repository-default token permissions. These bounded security risks require explicit owner acceptance or hardening before the PR is fully merge-ready.

Add concise docstrings to the public client API.

The new public exceptions, models, and client operations lack the required in-code API documentation.

• infrahub_sync/client/errors.py#L10-L10: add concise docstrings to each public exception subclass.
• infrahub_sync/client/models.py#L52-L59: add concise docstrings to each public request and resource model.
• infrahub_sync/client/client.py#L143-L157: add concise docstrings to every public SyncClient operation.

As per coding guidelines, "**/*.py: Prefer explicit types on new or changed code; public functions and classes get concise docstrings."

Security Misconfiguration (CWE-732): Incorrect Permission Assignment for Critical Resource

Declare least-privilege token permissions on this workflow.

Set permissions: contents: read at the workflow level. The called workflows already declare this scope, but the caller should not rely on repository-wide defaults. workflow_dispatch does not itself widen token permissions.

Inline comments:
In `@infrahub_sync/client/client.py`:
- Line 339: Update wait_for_run around the get_run call to pass the remaining
wait budget as the poll request timeout, ensuring _send uses it instead of the
client-wide HTTPX timeout. After get_run returns, recheck the deadline before
continuing so a stalled response cannot extend the requested wait_for_run
timeout.
- Around line 120-123: Update the service URL validation around
authority_invalid in the client initialization flow to reject every scheme
except HTTPS, while preserving the existing host and credential checks and
ClientInputError behavior.

In `@infrahub_sync/client/models.py`:
- Around line 206-214: Update OrchestrationSummary timestamp fields
submitted_at, claimed_at, stalled_at, cancellation_requested_at,
cancellation_recovery_deadline_at, cancellation_acknowledged_at, and terminal_at
with a field_validator that applies the existing _timezone helper, matching the
validation used by other resource models and rejecting naive datetime values.

In `@infrahub_sync/managed/config_routes.py`:
- Line 115: Add concise docstrings to the public configuration methods register,
validate, and the other methods in the affected configuration API. Each
docstring should state the method’s operation, its typed return result, and
pagination behavior where applicable, following the project’s existing
documentation style.

In `@tests/client/test_client.py`:
- Line 12: Raise the lower bound for the typing-extensions dependency to >=4.4.0
in the project dependency declaration, ensuring the typing_extensions.override
import used by the tests is available while preserving the existing resolved
version and other constraints.

In `@tests/client/test_models.py`:
- Around line 16-22: Update
test_client_package_imports_no_product_or_service_module to recursively scan
client Python modules and resolve ast.ImportFrom relative imports using
node.level before adding module names, so forbidden product or service imports
are detected consistently.

Addressed the two review-level nitpicks in ff91d35: all exported client models/errors and public SyncClient operations now have concise docstrings, and the dispatch workflow declares permissions: contents: read. The same commit documents the accepted HTTP/HTTPS transport policy.
