feat(bundles): add Xquik read-only data source

[kriptoburak]

Summary

• Add Xquik to Langflow's lfx-bundles provider architecture.
• Support 6 read-only operations: tweet search, tweet lookup, user lookup, user search, user tweets, and trends.
• Provide Table, JSON, and Text outputs for tabular processing, structured flows, and prompt context.
• Add component documentation, migration metadata, package extras, and bundle-local tests.

Problem

Issue #13101 requests a reusable public X/Twitter data source. Generic API Request components can call these endpoints, but each flow must then reproduce authentication, operation-specific inputs, pagination, output normalization, and error handling.

This component keeps that behavior in one tested Langflow provider. It uses Langflow's manifest-less lfx.bundles discovery path and does not add a client dependency.

Safety & Behavior

• Read-only endpoints only.
• Fixed HTTPS API origin with redirects disabled.
• Path identifiers URL-encoded.
• API key stored in a secret input.
• Request timeouts and operation limits bounded to the public API contract.
• Provider and transport bodies excluded from error payloads.
• Returned X content documented as untrusted input.

Validation

• uv run --no-sync pytest src/bundles/lfx-bundles/tests/test_xquik_component.py --cov=lfx_bundles.xquik.xquik --cov-report=term-missing -q: 37 passed, 100% statement coverage.
• Isolated extension migration, loader, and discovery suites: 206 passed.
• Direct runtime discovery: ext:xquik:XquikComponent@official loaded from lfx-bundles 1.1.16.
• Full changed-file pre-commit suite passed.
• Bundle release plan reports lfx-bundles 1.1.15 to 1.1.16 as ready.
• Production Docusaurus build completed successfully.
• uv lock --check and git diff --check passed.

This supersedes #13306, which GitHub cannot reopen after its branch refresh.

Closes #13101

Summary by CodeRabbit

• New Features

  • Added an Xquik component for read-only X/Twitter searches, user lookups, tweet retrieval, and trends.
  • Supports table, JSON, and text output formats with configurable operation-specific inputs.
  • Added API key authentication and clear handling for invalid, empty, or failed requests.
  • Added migration support for the new component.

• Documentation

  • Added installation, setup, usage, API, and data-handling documentation.
  • Added Xquik to the bundle directory and navigation.

• Chores

  • Updated the bundle package to version 1.1.16 and included the Xquik optional extra.

Walkthrough

Adds the Xquik bundle as a packaged Langflow component for read-only X/Twitter data operations. It includes API request handling, output formats, validation, tests, package wiring, migration metadata, documentation, and navigation updates.

Changes

Xquik bundle

Layer / File(s)	Summary
Bundle release and export wiring src/bundles/lfx-bundles/pyproject.toml, src/bundles/lfx-bundles/src/lfx_bundles/xquik/__init__.py, pyproject.toml	Publishes lfx-bundles version 1.1.16, adds the xquik extra, updates aggregate extras, raises the project minimum bundle version, and exports XquikComponent.
Component contract and operation configuration src/bundles/lfx-bundles/src/lfx_bundles/xquik/xquik.py	Defines supported Xquik operations, inputs, outputs, dynamic field visibility, URL construction, required-field validation, and bounded numeric parameters.
Request execution and output normalization src/bundles/lfx-bundles/src/lfx_bundles/xquik/xquik.py, src/bundles/lfx-bundles/tests/test_xquik_component.py	Adds authenticated asynchronous requests, timeout and redirect settings, error handling, payload normalization, table/JSON/text outputs, and mocked tests.
Documentation, navigation, and release registration docs/docs/Components/bundles-xquik.mdx, docs/docs/Lfx/extensions-bundle-list.mdx, docs/sidebars.js, src/lfx/src/lfx/extension/migration/migration_table.json, scripts/ci/release_inventory_contract.json	Documents installation and API usage, adds the bundle to documentation navigation, registers its extension migration target, and updates the release inventory.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 65395

The PR adds the Xquik read-only data source and related documentation; the implementation is otherwise mergeable, with a bounded documentation follow-up needed to capitalize specific Langflow Components and Flows consistently.

Excessive Mock Usage Warning	✅ Passed	The added tests use one reusable httpx.MockTransport seam for external HTTP only; component logic, request assertions, normalization, outputs, and errors run as real code.

Addressed the actionable automated findings on the current head:

• Added xquik to the release inventory in a73bf6635.
• Removed the redundant async markers in 6539579c6; the repository already uses automatic async discovery.

The component suite passes all 37 tests with 100% component coverage, and the 146 release-script tests pass locally. The capitalization suggestion was evaluated against current Langflow bundle docs and resolved with repository-style evidence.
