docs: update predict terminology to run

[markphelps]

Updates documentation to use 'run' terminology instead of 'predict', following the recent rename of the predict command to run.

Changes include:

• Updated all user-facing docs (README, getting-started guides, python.md, yaml.md, deploy.md, training.md, environment.md, wsl2 guide)
• Updated CLI help text in Go source for cog run and cog serve
• Regenerated docs/cli.md and docs/llms.txt

API endpoint references (/predictions) and the deprecated predict field documentation were intentionally left unchanged.

I've reviewed all the changed files in PR #3026. This is a documentation-only PR that updates terminology from "predict" to "run" following the recent command rename.

Summary of changes:

• Updates all user-facing docs to use cog run instead of cog predict
• Updates Python API references from predict() to run() and Predictor to Runner
• Updates CLI help text in Go source files
• Regenerates docs/cli.md and docs/llms.txt
• Maintains backward compatibility notes for deprecated terms
• Correctly preserves API endpoint references (/predictions) as intended

The changes are comprehensive, consistent, and maintain proper backward compatibility documentation. All modified files show appropriate terminology updates without breaking existing functionality.

LGTM
