chore: remove pre-commit rule

[mateo-berri]

Some users do not use make pre-commit as it is a multi-minute process. I personally use it, but I want users themselves to decide whether to pre-commit before each commit or not, based on what works best for them

Greptile Summary

This PR makes the CI-equivalent local check optional rather than requiring it before every commit.

• Removes the instruction to run make check before every commit, including merge commits.
• Retains guidance about the command alias and its saved log output.

Confidence Score: 5/5

The PR appears safe to merge because it makes an intentionally documented workflow-policy change without affecting runtime code or introducing contradictory guidance.

The sole change removes a deliberately unwanted mandate while retaining accurate information about invoking and inspecting the optional check.

Important Files Changed
