feat(swift): comprehensive Swift ecosystem filters (#848)

[pszymkowiak]

Summary

Adds 5 TOML filters + rewrite rules for the Swift ecosystem. Closes #848.

Command	Filter	Savings
swift test	Strip passing tests, show failures + summary	80-85%
swift package resolve/update	Strip Fetching/Resolving noise	80-90%
swift run	Strip build noise, show app output	70-80%
swiftlint	Strip Linting noise, show violations	75%
swiftformat	Short-circuit on no changes, show changed files	70%

Rewrite rules added

• swift (build|test|run|package) → rtk swift ...
• swiftlint → rtk swiftlint
• swiftformat → rtk swiftformat

Also fixes

• Pre-existing cargo fmt issues in diff_cmd.rs, init.rs
• Pre-existing clippy warning in rake_cmd.rs (map_or → is_some_and)

Test plan

• 1119 tests passed, 0 failed
• cargo fmt clean
• cargo clippy clean
• All 5 TOML filters have inline tests (10 test cases total)
• Rewrite tests for swift test, swiftlint, swiftformat, swift package

Hey

We are cleaning up the codebase and improving the project structure for better onboarding. As part of this effort, PR #826 reorganizes src/ from a flat layout into subfolders.

No logic changes — only file moves and import path updates.

What you need to do

Rebase your branch on develop when receiving this comment:

git fetch origin && git rebase origin/develop

Git detects renames automatically. If you get import conflicts, update the paths:

use crate::git;        // now: use crate::cmds::git::git;
use crate::tracking;   // now: use crate::core::tracking;
use crate::config;     // now: use crate::core::config;
use crate::init;       // now: use crate::hooks::init;
use crate::gain;       // now: use crate::analytics::gain;
