Summary

Three docs were failing the doc-codeblocks CI job because they contain illustrative code blocks that can't be executed in CI:

Net diff: 10 lines, each just appends skip to a fence opener.

Greptile Summary

This PR fixes CI failures in the doc-codeblocks job by appending skip to code fence openers for illustrative examples that cannot be executed in CI (e.g., hardware-dependent shell commands and configuration snippets that require a live robot environment).

• Six Python code blocks in nav_stack.md and visualization.md are marked skip, preventing the CI runner from attempting to execute partial configuration snippets.
• Two shell blocks in g1/index.md are marked skip to avoid executing device-specific SSH and curl | sh commands during CI.
• A stray blank line is removed from navigation/readme.md (cosmetic only).

Confidence Score: 5/5

Documentation-only change that adds skip markers to code fences; no logic, runtime behavior, or executable code is modified.

Every change in this PR is a one-token addition to a Markdown code fence opener. The underlying code examples are left entirely intact; only the CI runner's handling of them changes. There is nothing here that could introduce a runtime regression or a behavioral change.

No files require special attention.

Important Files Changed

Filename	Overview
docs/capabilities/navigation/nav_stack.md	Six illustrative Python code blocks marked skip to prevent CI execution; no content changes.
docs/capabilities/navigation/readme.md	Cosmetic-only change: removes a blank line after the heading.
docs/platforms/humanoid/g1/index.md	Two shell code blocks (SSH + curl install commands) marked skip to avoid CI execution against hardware.
docs/usage/visualization.md	Two Python code blocks marked skip; no content changes to the examples themselves.
