[huang-julien]

Closes #

Summary by CodeRabbit

• Chores
  • Code formatting verification (fmt) has been added to the automated CI pipeline so formatting checks run alongside existing build and test tasks.
  • A project-level formatting target was introduced to enable centralized format-checking and caching, ensuring consistent formatting verification across the workspace.

📝 Walkthrough

Walkthrough

Adds a new Nx fmt target that runs yarn fmt:check and includes that target in the CI ALL_TASKS list so formatting checks run as part of the NX task runner in GitHub Actions.

Changes

Cohort / File(s)	Summary
Nx project target code/project.json	Added new targets.fmt using nx:run-commands with options.command: "yarn fmt:check", cache: true, and inputs: ["sharedGlobals", "{workspaceRoot}/**/*"].
CI workflow .github/workflows/nx.yml	Inserted fmt into the ALL_TASKS environment variable so fmt is included when yarn nx run-many -t $ALL_TASKS and when Nx agents are stopped after ALL_TASKS.

In `@code/project.json`:
- Around line 6-12: The fmt target in project.json runs "yarn fmt:check" but its
inputs only include "default", risking cache staleness; either expand the
"inputs" to include workspace-wide files that the formatter touches or restrict
the command to the project directory by adding a "cwd": "{projectRoot}" option
to the fmt target (matching the lint target pattern). Locate the "fmt" target
entry and update its "inputs" to cover the workspace files used by oxfmt (e.g.,
add shared/workspace inputs) or add the "cwd": "{projectRoot}" key alongside
"options" so the yarn fmt:check command only checks the projectRoot, then run
the formatter check to verify caching behavior.
