* Bring Hosted-Toolbox sample to parity with sibling hosting samples Adds the standard scaffolding files (.env.example, agent.yaml, agent.manifest.yaml, Dockerfile, Dockerfile.contributor) that every other 04-hosting Foundry sample ships but Hosted-Toolbox lacked. Fixes the toolbox name environment variable: reads TOOLBOX_NAME instead of the platform reserved FOUNDRY_TOOLBOX_NAME so it survives agent create, and aligns the default to my-toolset. Rewrites the README to the standard section layout with PowerShell fenced commands, and adds Using-Samples READMEs documenting why the client REPLs exist. Renames Azure AI Foundry to Foundry across the 04-hosting sample READMEs and comments for consistent product naming. * Address PR review: accurate docs and TOOLBOX_NAME in ToolboxMcpSkills - SimpleAgent README: correct the demo banner to the real per-agent URL the client prints (https scheme and the /api/projects/<project> segment). - Hosted-Toolbox Program.cs: move FOUNDRY_MODEL out of the Required block into Optional since it has a gpt-4o default and an AZURE_AI_MODEL_DEPLOYMENT_NAME fallback. - Hosted-ToolboxMcpSkills: switch the toolbox name from the reserved FOUNDRY_TOOLBOX_NAME to TOOLBOX_NAME across Program.cs, .env.example, agent.yaml, agent.manifest.yaml and README so it is deployable via the manifest, matching the other toolbox samples.
