Refactor: Replace SKIP_FETCH_TOOLS_EXAMPLE env variable with per-tool configuration

[ryoppippi]

Summary

The SKIP_FETCH_TOOLS_EXAMPLE environment variable pattern is an anti-pattern. This should be replaced with per-tool configuration.

Context

From PR #148 review comment by @glebedel:

It seems that this should be a per tool configuration rather than based on an env variable

#148 (comment)

Affected Files

• examples/human-in-the-loop.ts
• Any other files using SKIP_FETCH_TOOLS_EXAMPLE or similar env-based feature toggles

Current Implementation

if (process.env.SKIP_FETCH_TOOLS_EXAMPLE) {
  // skip behaviour
}

Proposed Changes

Replace environment variable checks with explicit per-tool or per-instance configuration:

const toolset = new StackOneToolSet({
  skipFetch: true, // or similar configuration option
});

Or use per-tool configuration as appropriate for the use case.

Closing as the SKIP_FETCH_TOOLS_EXAMPLE environment variable no longer exists in the codebase - it was already removed.
