0.6.0

This release brings Linux and Android support, a much richer rule composition vocabulary, new recency/cooldown conditions, and finer-grained trigger throttling — plus rule introspection APIs and documentation improvements.

⚠️ Breaking changes

• Dropped support for Swift 5.9 and 5.10. RuleKit now requires Swift 6.0+ (Xcode 16+).

🐧 Linux & Android support

RuleKit was previously Apple-only. It now builds and runs on Linux and Android (#2):

• Replaced OSLog with swift-log — RuleKit's first dependency.
• Triggers now fire on the main actor by default instead of DispatchQueue.main (an explicit .dispatchQueue(_) option is still honored), avoiding hangs on platforms without a drained main queue. Behavior is unchanged on Apple platforms.
• .groupContainer is gated to Apple platforms; use .url(_) elsewhere.

✨ Rule composition

• && and || operators to compose rules, as shorthands for .allOf([...]) and .anyOf([...]).
• .not(_:) and the ! prefix operator to negate a rule, completing the logic alongside .allOf / .anyOf.
• noneOf(_:) — fulfilled when none of the given rules are, the complement of anyOf.
• atLeast(_:of:) — a k-of-n quorum rule that can't be expressed cleanly with allOf / anyOf alone.
• .always and .never constant rules, useful as placeholders or for conditional composition.

⏱️ Recency & cooldown rules

• event(_:donatedWithin:) and event(_:notDonatedFor:) — time-window conditions on an event's last donation (recency and cooldowns), taking a TimeInterval in seconds.
• event(_:atLeast:) shorthand for the common "donated at least N times" condition.
• timeSinceFirst / timeSinceLast computed properties on Event.Donations.
• Donations.firstSeenInCurrentVersion — whether an event's first donation happened in the current app version (replacing the hand-written appVersion comparison from the README).

🔁 Trigger frequency

• Added .every(_:count:) to TriggerFrequencyOption.Frequency, allowing throttle windows like "every 7 days" instead of only fixed calendar cases.

🛠️ API ergonomics & introspection

• setRule now accepts variadic options and a trailing-closure ruleset, so a single option no longer needs to be wrapped in an array (array-based overloads remain for source compatibility).
• registeredRuleNames and isRuleRegistered(named:) — read-only APIs to list registered rule identifiers (in registration order) and check membership, keyed by the same name as removeRule(named:).

📚 Documentation

• Added DocC documentation and improved the README.
