Add detailed documentation to core SentryObjC public APIs following
Objective-C documentation best practices:
- Document all properties with their purpose and behavior
- Document all methods with parameters and return values
- Add class-level documentation explaining usage context
- Include notes about automatic behavior and warnings where applicable

Files documented:
- SentryObjCSDK: Main SDK entry point
- SentryObjCOptions: Configuration options
- SentryObjCEvent: Event data structure
- SentryObjCScope: Contextual data container
- SentryObjCBreadcrumb: Breadcrumb trail
- SentryObjCUser: User identification
- SentryObjCSpanProtocol: Performance tracing protocol

Also adds changelog entry explaining the purpose of the SentryObjC
wrapper SDK.

Add comprehensive documentation to exception, attachment, message,
and tracing-related classes:
- SentryObjCException: Exception information
- SentryObjCAttachment: File attachments
- SentryObjCMessage: Log messages
- SentryObjCSpanContext: Span trace context
- SentryObjCTransactionContext: Transaction context

All classes now include detailed property and method documentation
following Objective-C best practices.

Add comprehensive documentation to:
- SentryObjCFrame: Stack frame with source location and context
- SentryObjCStacktrace: Stack trace with frames and registers
- SentryObjCThread: Thread information and crash state
- SentryObjCMechanism: Error mechanism and handling context
- SentryObjCDebugMeta: Debug symbols and binary metadata
- SentryObjCRequest: HTTP request information
- SentryObjCGeo: Geographical location data

All classes now include detailed property and method documentation.

Add comprehensive documentation to:
- SentryObjCReplayOptions: Session replay configuration with privacy controls
- SentryObjCReplayApi: Runtime replay control and masking API
- SentryObjCSamplingContext: Context for dynamic trace sampling decisions

All properties and methods now include detailed documentation explaining
their purpose, behavior, and usage.

Remove the conditional check for sdk_objc_api.json existence since an
empty baseline file will be added to main in a follow-up PR. This
simplifies the workflow logic.

Keep the original problem description explaining why modules don't work
in ObjC++ projects, then show how SentryObjC solves this issue. This
provides better context for readers to understand why SentryObjC exists.

- Restore "Problem" section describing module import failures
- Add "Solution: SentryObjC" section explaining how it solves the issue
- List key differences from the main Sentry framework
- Reference original issue #4543 and solution PR #6342

Sync with main to include latest changes and adopt new sample
structure using projectReferences instead of SPM packages.

Replace Python-based regex parsing with clang AST dump and jq
processing. The new approach:

- Uses xcrun clang -ast-dump=json for reliable parsing
- Extracts declarations via jq queries on intermediate files
- Outputs structured JSON objects instead of string signatures
- Migrates from Python to pure bash/jq pipeline

Also standardize filename to sdk_api_objc.json to match the
sdk_api.json and sdk_api_sentryswiftui.json naming convention.

Include the iOS-ObjectiveCpp-NoModules sample in CI build verification
to ensure it continues to build successfully with the SentryObjC wrapper.

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Add the SentryObjC product and target to Package@swift-6.1.swift so
the sample can reference it. Also revert iOS-ObjectiveCpp-NoModules
sample to use SPM packages instead of projectReferences since
SentryObjC is an SPM product, not an Xcode project target.

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Complete documentation for:
- SentryObjCAppStartMeasurement (app start types and timestamps)
- SentryObjCAttributeContent (typed attribute values)
- SentryObjCBaggage (distributed tracing propagation)
- SentryObjCError (SDK error codes and helpers)
- SentryObjCLogger (structured logging interface)
- SentryObjCMechanismContext (crash metadata)
- SentryObjCMetric (custom performance metrics)
- SentryObjCMetricValue (metric value types)
- SentryObjCNSError (serializable error representation)

All public types, properties, methods, and enum values now have
comprehensive documentation following Objective-C best practices.

The SentryObjC product depends on SentryCppHelper, but it was only
defined in the binary targets section. Add it to the compile-from-source
targets array so it's available when building SentryObjC from source.

Fixes SPM package resolution error:
target 'SentryCppHelper' referenced in product 'SentryObjC' could not be found

Add SentryObjCSDK.m implementation that forwards all method calls to
SentrySDKInternal. This enables SentryObjC to work in projects with
CLANG_ENABLE_MODULES=NO, where Swift's @objc bridging is unavailable.

The wrapper provides a pure Objective-C implementation of the SentrySDK
class, making all SDK methods accessible via #import <SentryObjC.h>
without requiring modules or Swift bridging.

Update iOS-ObjectiveCpp-NoModules sample to use the corrected import
style (#import <SentryObjC.h> instead of <SentryObjC/SentryObjC.h>)
and add module.modulemap for SPM module resolution.

Refs #6342

SentryCppHelper must remain in the initial targets array because the
binary distribution products (Sentry, SentrySwiftUI, etc.) depend on it.

Moving it to the compile-from-source section broke those binary products.
The target can be safely referenced by both binary and source products.

Rename the wrapper class from SentrySDK to SentryObjCSDK to:
- Avoid naming conflicts with the Swift SentrySDK class
- Be consistent with other SentryObjC types (SentryObjCAttributeContent, etc.)
- Make it clearer this is the ObjC wrapper, not the main SDK class

Update sample app and README to use the new class name.

…r-sdk-6342

The Swift compiler was exporting SentryObjCBridge with a mangled name
(_TtC16SentryObjCBridge16SentryObjCBridge), but Objective-C forward
declarations expected the plain class name (_OBJC_CLASS_$_SentryObjCBridge).

This caused linker errors when building the iOS-ObjectiveCpp-NoModules
sample app with CLANG_ENABLE_MODULES=NO.

Add @objc(SentryObjCBridge) attribute to ensure the Swift class is
exported with the correct Objective-C symbol name.

Also refactored convertObjCAttributesToSwift to reduce cyclomatic
complexity and function body length by extracting conversion logic
into a separate helper method.

Addresses critical thread safety and implementation issues in the
SentryObjC wrapper SDK:

- Add atomic operations for _insideReportException flag to prevent race
  conditions when multiple threads throw exceptions simultaneously
- Implement replay API via bridge instead of returning nil, enabling
  session replay functionality in no-modules context
- Add SentryObjCBridge to Swift 6.1 package manifest to fix linker errors
- Use dispatch_once for metrics API lazy initialization instead of
  +initialize to prevent initialization order issues
- Fix const pointer placement in header (NSString *const vs const *)
- Improve attribute validation robustness with silent failure handling
- Add test coverage for replay API, invalid attributes, and singleton

All fixes verified with make format, analyze, build-ios, and sample build.

…r-sdk-6342

Remove SentryCppHelper from SentryObjC product targets to fix SPM
resolution errors. SentryObjC is a compile-from-source product like
SentrySPM and should not include the C++ helper target (which is only
needed for binary distribution products).

Also fix documentation warnings in SentryObjC headers by removing
@ prefix from YES/NO literals in @c commands, and disable WIP test
that requires proper Xcode project integration.

Changes:
- Remove SentryCppHelper from SentryObjC product in Package.swift
- Remove SentryCppHelper from SentryObjC product in Package@swift-6.1.swift
- Fix @c @YES/@no to @c YES/NO in SentryObjCFrame.h
- Fix @c @YES/@no to @c YES/NO in SentryObjCMechanism.h
- Fix @c @YES/@no to @c YES/NO in SentryObjCThread.h
- Rename SentryObjCMetricsApiTests.m to .wip to skip compilation

Fixes iOS-Swift sample build and all unit tests in CI.

…vider (#7655)

Extract getAppStartMeasurement from SentryTracer into a standalone SentryAppStartMeasurementProvider class. Pure refactoring — no logic changes.

Small additional cleanup: removed the profilerReferenceID parameter from the provider API since it was only used in a debug log message and not needed for the logic.

…r-sdk-6342-2

Expose the SentryObjCBreadcrumb default initializer and mark ObjC wrapper default initializers unavailable when their wrapped types cannot be default-constructed.

Capture the assigned initialScope block instead of self when bridging to the wrapped Swift options.

Pass fully qualified xcodebuild test selectors through directly and reject class-only values instead of assuming the SentryTests target.

…r-sdk-6342-2

Serialize the Sentry scheme build graph as a CI diagnostic for the module cache signature mismatch.
