Fix typos in documentation and configuration files

[leopardracer]

This PR fixes several typos across different files:

• docs/concepts/llms.mdx: Fixed typo "architecure" -> "architecture" in phi-3.5-moe-instruct model description
• src/crewai/cli/install_crew.py: Fixed typo "envirorments" -> "environments" in comment
• tests/cassettes/test_lite_agent_structured_output.yaml: Fixed typo "strucutred" -> "structured" in test content

These changes improve documentation readability and code consistency.

Summary of Key Findings
-----------------------
This PR consists of three isolated typo corrections across the repository — in a test cassette YAML file, a Python CLI source file, and a Markdown documentation file.

1. In `tests/cassettes/test_lite_agent_structured_output.yaml`, the user prompt was corrected from "strucutred" to "structured".
2. In `src/crewai/cli/install_crew.py`, a comment spelling error "enviorments" was fixed to "environments".
3. In `docs/concepts/llms.mdx`, the word "architecure" was corrected to "architecture" in a markdown table row.

All changes improve textual clarity and professionalism. None modify code logic, functionality, or introduce risks.

Specific Code Improvements with Examples
----------------------------------------

- **Test cassette correction for input clarity:**
  ```yaml
  - "content": "What is the population of Tokyo? Return your strucutred output in JSON format..."
  + "content": "What is the population of Tokyo? Return your structured output in JSON format..."

This correction ensures accurate parsing and comprehension of test inputs for automated tests relying on precise strings.

• Comment typo correction in install_crew.py:

  -# on some enviorments we don't use this command but instead uv sync directly
  +# on some environments we don't use this command but instead uv sync directly

  Although a minor fix, it enhances maintainability and reduces potential confusion during onboarding or contributions.

  Suggestion: Consider adding a concise docstring to the install_crew function describing parameters and behavior to improve code self-documentation.

• Documentation table fix in llms.mdx:

  -| microsoft/phi-3.5-moe-instruct | 128K tokens | Advanced LLM based on Mixture of Experts architecure to deliver compute efficient content generation |
  +| microsoft/phi-3.5-moe-instruct | 128K tokens | Advanced LLM based on Mixture of Experts architecture to deliver compute efficient content generation |

  This change enhances professional presentation and avoids distracting orthographic errors.

Historical Context and Related PRs

Reviewing prior similar PRs reveals a recurrent pattern of small, focused typo corrections across tests, comments, and documentation, emphasizing crewAI’s commitment to quality and clarity without altering functionality.

From related past changes:

• Typos in test inputs can cause ambiguity or fragile tests.
• Comment fixes improve maintainability.
• Documentation corrections preserve professional user experience.

No controversial decisions or regressions were introduced by such typo fixes historically.

Implications for Related Files

• The test cassette file directly affects automated testing stability and readability.
• The CLI install source affects developer experience around environment-specific installations.
• The documentation file is user-facing content supporting learning and adoption.

Since these changes are nonfunctional typo corrections, there is minimal risk of unintended side effects or impact on dependent files or modules.

Improvement Suggestions

• Integrate automated spell checking into CI/CD:
  Employing spell checkers (e.g., codespell, markdownlint, or IDE plugins) can catch such minor typos before PR creation, reducing manual review overhead.

• Review neighboring lines for similar typos:
  Consider scanning entire files around corrected typos to catch other unnoticed errors in the same PR or a follow-up.

• Add docstrings where missing:
  For functions like install_crew, adding clear docstrings benefits maintainers and improves developer onboarding.

• Standardize documentation formatting:
  Consider uniform capitalization and terminology in tables (e.g., "Tokens" vs "tokens") for consistency.

Summary Table

File	Issue	Suggestion
tests/cassettes/test_lite_agent_structured_output.yaml	Typo in test input	Confirm no other typos in file
src/crewai/cli/install_crew.py	Typo in comment	Add docstring (optional)
docs/concepts/llms.mdx	Typo in documentation	Apply spellcheck to docs regularly

Conclusion

This PR is well-scoped, clean, and safe. It corrects simple but meaningful spelling errors that enhance clarity, professionalism, and test accuracy. No functional or behavioral impacts are present. Approval is recommended.

To reduce such issues in the future, establishing automated spelling checks and encouraging docstring use are advised.
