Rewrite maifetch in Rust

[MAUROCERON]

Closes #1.

/claim #1

This rewrites maifetch from Go to Rust while preserving the command-line/config behavior and the existing terminal output shape for the GBP 50 bounty issue.

What changed:

• replaced the Go module with a Cargo project and split the Rust code into a reusable library plus CLI binary
• kept MaiTea profile/play fetching through authenticated JSON requests
• migrated the small API wrapper surface for profiles, tracks, status, plays, all plays, best scores, all best scores, and pagination helpers
• preserved the response field coverage from the Go structs, including Japanese localized names, difficulty keys, play dates, and profile first/latest play markers
• preserved config precedence: config file, environment, then CLI overrides
• supports both documented MAITEA_* env vars and the previous MAIFETCH_* prefix
• supports the documented -a/--access-token flag and the previous hidden -t short token flag
• keeps recent score formatting, ANSI colors, and optional colored ASCII icon output

Validation run locally on the latest head:

• cargo fmt --check
• cargo +1.91.1-x86_64-pc-windows-gnu check
• cargo +1.91.1-x86_64-pc-windows-gnu clippy -- -D warnings

Fresh PR-head validation also confirms the combined logo/text output loop uses the fixed index < *_lines.len() bounds. A local MSVC check was blocked by this Windows environment missing link.exe; cargo test on GNU/gnullvm was also limited by local Windows linker availability, while GNU type-checking and clippy pass cleanly.

No private payout details are included here.

Follow-up: I expanded the Rust rewrite to cover the small MaiTea API wrapper too, not just the CLI path.

Added Rust equivalents for profiles, tracks, status, plays/all-plays, scores/all-scores, and pagination helpers, and split the project into a library plus CLI binary.

Validation after the update:

• cargo fmt
• cargo +stable-x86_64-pc-windows-gnu check
• cargo +stable-x86_64-pc-windows-gnu check --target x86_64-pc-windows-gnullvm

Actually I changed my mind the bounty to £75 and wanting a rewrite in zig. ensure there's testing
