Add sentry.replay_id attribute to logs

[denrase]

📜 Description

• Add sentry.replay_id to logs if replay id is set on scope
• Add sentry.replay_id and sentry._internal.replay_is_buffering if replay id is set on integration (buffer mode)

💡 Motivation and Context

I tried this with our sample app, but always got no session, and therefore not replayId, from the integration. Was expecting that we have a buffered session, but i'm probably not familiar with how this is implemented on iOS. I assumed the flow is similar to what we have on Android. NVM, this was on iOS 26 where it's disable. Works as expected on iOS < 26.

Closes #6133

💚 How did you test it?

Unit tests. Sample app.

📝 Checklist

You have to check all boxes before merging:

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

Bug: Replay Headers Cause Compilation Issues

The SentrySessionReplayIntegration headers are unconditionally imported in SentryPrivate.h. This causes compilation errors on platforms without replay support (e.g., watchOS, macOS without UIKit), as these headers contain code guarded by SENTRY_TARGET_REPLAY_SUPPORTED.

Bug: Test Crashes Due to Force-Unwrapping Nullable Property

Tests force-unwrap the sessionReplay property, which is now nullable. This creates a potential for test crashes if sessionReplay is nil, despite its nullable type declaration.

Having some trouble with accessing SentrySessionReplayIntegration in swift. Moved the files to SentryPrivate.h, like described in SWIFT.md, but now it is clashing with some build configurations and with SentryHybrid explicit module. Would appreciate some guidance here. 🙇

@noahsmartin is good candidate to answer this ⬆️

[denrase]

I was unsuccessful in exposing SentrySessionReplayIntegration/SentrySessionReplay to the Swift SDK, so I opted to add a helper to SentryHub+Private to access the integrations replayId.

I think this should be

Suggested change

	#if os(iOS) || os(tvOS)
	#if (os(iOS) || os(tvOS)) && !SENTRY_NO_UIKIT

[itaybre]

Probably the same here

Suggested change

	#if os(iOS) || os(tvOS)
	#if (os(iOS) || os(tvOS)) && !SENTRY_NO_UIKIT

[itaybre]

LGTM, once the build issue is fixed
