chore(workspace): apply rustfmt formatting across all crates

[Bhanudahiyaa]

Summary

Applies rustfmt formatting across the entire workspace so that cargo fmt --check passes cleanly on main.

This PR contains formatting-only changes produced by cargo fmt. No functional or behavioral changes were introduced.

Motivation

cargo fmt --check currently fails with 489 formatting diffs across many files, which blocks the CI quality gate defined in CONTRIBUTING.md.

Bringing the repository to a clean rustfmt state ensures that future PRs are not blocked by formatting issues.

Changes

• Ran cargo fmt across the entire workspace.
• Reformatted 134 files across 14 crates.
• Changes are strictly formatting-related:
• line wrapping of long expressions
• import list formatting
• trailing commas
• whitespace normalization

No logic or behavior changes were introduced.
