Summary

Fills in the missing "published crate" hygiene. No runtime behaviour change — the biggest chunk of diff is a project-wide cargo fmt --all to make the new CI's format check pass.

Licensing

• Added LICENSE. Cargo.toml declared license = "MIT" but no file was checked in. Added the standard MIT text.
• README license section was a literal placeholder ([Add your license information here]) — replaced with a link to LICENSE.

Cargo metadata

Added authors, repository, homepage, readme, keywords, categories, and rust-version = "1.70" to [package]. This makes cargo publish produce a useful crates.io page instead of a stub.

CI

• New .github/workflows/ci.yml. The only existing workflows (release.yml, publish-crates.yml) run on git tags, so regular PRs got zero automated validation. The new workflow runs on every push/PR:
  • Installs libclang-dev / clang so frida-sys' bindgen build can find libclang.
  • cargo fmt --all -- --check
  • cargo clippy --all-targets (does NOT pass -D warnings — the pre-existing tree has 28 warnings; tightening is a separate cleanup).
  • cargo build
  • cargo test --all (all 18 existing unit tests pass).

README polish

• Added centred header with License / crates.io / Rust badges.
• Replaced two your-username placeholders in clone URL and issues link with eunhhu.

Formatting

• Ran cargo fmt --all. Only touches src/gum/commands/*.rs, src/gum/memory.rs, src/gum/store.rs, src/gum/vzdata.rs. Pure formatting; no logic changes.

Review & Testing Checklist for Human

• Confirm the cargo-fmt diff is indeed pure formatting (spot-check src/gum/commands/disasm_cmds.rs and src/gum/memory.rs).
• cargo build && cargo test still passes locally (mirrors what CI does).
• You're OK with clippy running as a warn-only step for now (the repo has 28 pre-existing warnings; tightening is out of scope for this PR).

Notes

• The existing release.yml / publish-crates.yml workflows are unchanged; they continue to run only on v*.*.* tags.
• No dependency version changes.
