Walkthrough

The PR removes Dockerfile configurations and Docker deployment documentation from four example projects (email_phishing_analyzer, agno_personal_finance, simple_calculator, simple_web_query), eliminating containerized build instructions and related deployment guidance while updating associated README files.

Changes

Cohort / File(s)	Summary
Dockerfiles Removal examples/evaluation_and_profiling/email_phishing_analyzer/Dockerfile, examples/frameworks/agno_personal_finance/Dockerfile, examples/getting_started/simple_calculator/Dockerfile, examples/getting_started/simple_web_query/Dockerfile	Removed entire Dockerfile configurations that previously defined multi-stage container builds with virtual environment setup, package installation, configuration file mapping, and NAT server entrypoints.
Docker Deployment Documentation Removal examples/evaluation_and_profiling/email_phishing_analyzer/README.md, examples/frameworks/agno_personal_finance/README.md, examples/getting_started/simple_calculator/README.md	Removed Deployment-Oriented Setup sections including Build the Docker Image, Run the Docker Container, Test the API, and Expected API Output subsections; eliminated Docker prerequisites and related guidance.
Installation and API Key Setup Updates examples/getting_started/simple_web_query/README.md	Restructured table of contents; replaced Prerequisites and Deployment-Oriented Setup entries with Install this Workflow and Set Up API Keys; removed Docker Quickstart section; added instructions for package installation and NVIDIA API key configuration.

54-55: Add a blank line after the ### Set Up API Keys heading for consistency and compatibility.

You should put blank lines before and after a heading for compatibility. The ### Install this Workflow heading (Line 46) correctly has a blank line before its content, but ### Set Up API Keys jumps straight to the paragraph on the next line.

✏️ Proposed fix

 ### Set Up API Keys

 If you have not already done so, follow the [Obtaining API Keys](../../../docs/source/get-started/quick-start.md#obtaining-api-keys) instructions to obtain an NVIDIA API key.

The "### Set Up API Keys" heading lacks a blank line after it, breaking
consistency; edit the README so that the "### Set Up API Keys" heading has an
empty line after the heading (and ensure there is a blank line before the
heading if missing) so the paragraph below starts after a blank line—look for
the literal heading "### Set Up API Keys" and insert the missing blank line to
match the other headings like "### Install this Workflow".
