This commit introduces a **new capability** for **build performance observability** by adding a dedicated Azure DevOps pipeline and associated tooling within the `build-cli` package. This **feature addition** collects build metrics from ADO, processes them, and generates an interactive HTML dashboard, providing summary statistics, trend charts, and detailed stage/task duration breakdowns. The new pipeline, defined in `build-performance-observability.yml`, runs daily to monitor both PR and internal builds, publishing the dashboard as an artifact. This significantly enhances **developer tooling** by offering critical insights into build times, enabling proactive identification of regressions and optimization of the overall CI/CD process.

This commit **fixes** an issue within the **test-service-load** package by ensuring that the `disableSchemaUpgrade` option is consistently set to `false` for all **stress tests**. Specifically, it modifies the `optionsMatrix.ts` file to enforce this configuration, which is crucial for scenarios where all connected clients are expected to share the same schema upgrade behavior. This adjustment improves the reliability and consistency of **stress test execution**, preventing potential misconfigurations that could affect test outcomes. The change ensures that the testing environment accurately reflects intended multi-client scenarios.

This commit introduces a **new capability** to the **`ContainerRuntime`** by adding a `disableSchemaUpgrade` option to `ContainerRuntimeOptions`. When enabled, this option prevents the runtime from sending `DocumentSchemaChange` operations and throws an error on incoming ones, effectively **disabling document schema upgrades**. This **maintenance** feature is primarily implemented within the **`DocumentsSchemaController`** to control schema message processing. It is particularly useful for applications that do not require schema evolution, ensuring greater stability by eliminating potential mid-session errors related to schema changes.

This commit **introduces a new Azure DevOps pipeline configuration** for **build performance observability**, adding the `tools/pipelines/build-performance-observability.yml` file. This is a **new feature** that serves as a **placeholder pipeline**, establishing the foundational infrastructure within the **CI/CD pipelines** subsystem. While not yet fully functional, this initial setup is critical for enabling future iteration and development on a dedicated test branch, laying the groundwork for comprehensive build performance monitoring.

build: Update build-tools dependencies & pnpm dedupe (#25990)

bump(build-tools): Bump build-tools packages to 0.62.0 (#25970)

This commit performs a **security update** by upgrading the `glob` dependency to version `10.5.0`. This change specifically addresses a known **security vulnerability** present in the previous `10.4.5` version, enhancing the project's overall **security posture**. The update primarily impacts the project's **dependency management** by modifying `pnpm` lockfiles, ensuring all internal consumers utilize the patched `glob` package without requiring any code changes.

This commit **re-enables** the `ConsensusOrderedCollection` distributed data structure in the **`local-server-stress-tests` package**. It resolves a prior issue by enhancing the `synchronizeClients` function in `packages/test/local-server-stress-tests/src/localServerStressHarness.ts` with a timeout mechanism, crucial for ensuring all operations are processed for `ConsensusOrderedCollection`. This **test maintenance** and **bug fix** significantly improves the reliability and coverage of stress tests, which previously failed consistently when this DDS was active.

This commit **removes `ConsensusOrderedCollection`** from the **local server stress test suite** in `packages/test/local-server-stress-tests`. The change specifically **removes a `setTimeout` workaround** from the `synchronizeClients` logic within `localServerStressHarness.ts`, which was intended to prevent containers from being left in a dirty state. This **test maintenance** action addresses **non-deterministic CI failures** and improves the reliability of the test pipeline by temporarily disabling a problematic test.

This commit introduces comprehensive **fuzz testing** for the `ConsensusRegisterCollection` Distributed Data Structure (DDS) within the `packages/dds/register-collection` module. It adds new test suites in `consensusRegisterCollection.fuzz.spec.ts` and defines a `baseRegisterCollectionModel` and associated utilities in `fuzzUtils.ts` to generate and validate randomized operations. This **testing enhancement** also integrates the new fuzz model into the `packages/test/local-server-stress-tests` framework, enabling more robust validation of the DDS's behavior under concurrent and high-load conditions. This **maintenance** work significantly improves the **quality assurance** and reliability of the `ConsensusRegisterCollection` by uncovering potential edge cases and concurrency bugs.

This commit introduces comprehensive **fuzz and local server stress testing** for the **`ConsensusOrderedCollection` DDS**, significantly enhancing its validation. A key **enabling change** involved modifying the `applyStashedOp` method in `consensusOrderedCollection.ts` to an empty implementation, which is crucial for supporting rehydration scenarios during testing. This **new testing capability** integrates the DDS into the existing local server stress test harness and includes a minor **fix** in `localServerStressHarness.ts` to ensure all operations are processed. The work improves the robustness and reliability validation of `ConsensusOrderedCollection` under various complex conditions.

This commit performs a **dependency update** for the project's `build-tools` to version `0.60.0`, aligning with the latest release. Concurrently, it **updates generated files** within the `typetest` module to incorporate a new heading introduced in recent changes. This **maintenance** work ensures the project leverages the most current build tooling and maintains consistency in automatically generated code, primarily impacting the **build system** and **testing infrastructure**.

bump(build-tools): Bump build-tools packages to 0.61.0 (#25831)

This commit **fixes** an issue within the **build-tools** package by modifying the **typetest generation command** to strip pre-release and build metadata from version strings in generated file headers. Specifically, the logic in `build-tools/packages/build-cli/src/commands/generate/typetests.ts` now ensures that only the core version (e.g., `1.2.3` from `1.2.3-foo`) is used. This **maintenance** change is crucial for preventing **CI builds from unexpectedly modifying typetest files**, thereby enhancing build stability and consistency across different environments.

Bump build-tools packages to 0.60.0 (#25816)

Update typetests after 2.71.0 release (#25801)

This commit performs a **maintenance** update by **bumping the version of numerous client packages** from 2.71.0 to 2.72.0. This broad update affects various modules, including **Distributed Data Structures (DDS)**, **drivers**, **runtime components**, and **testing utilities** across the client-side codebase. The change ensures version consistency across the project's client ecosystem, preparing for the next release cycle. This is a routine version update, generated automatically, with no functional code changes.

This commit **adds the official release notes and changelogs** for the **2.71.0 release**, specifically updating the `RELEASE_NOTES/2.71.0.md` file. It details **new features and SharedTree DDS changes** introduced in this version, providing a comprehensive overview for users. This **documentation update** is a crucial **maintenance task** that informs the community about the latest changes and improvements in the **client** codebase.

This commit **refactors** various **DDS and framework components** by adding short codes to assertion messages across several packages. Specifically, it enhances error diagnostics within `packages/dds/counter`, `packages/dds/ordered-collection`, `packages/dds/tree`, and `packages/framework/presence` by tagging existing assertions. This **maintenance** task improves the clarity of assertion failures, making debugging easier for developers, and updates the `assertionShortCodesMap` accordingly. This work is part of the preparation for the upcoming 2.71.0 release.

This commit introduces **rollback support** for the **`SharedCounter`** Distributed Data Structure (DDS), enabling optimistic `increment` operations to be reverted by applying an inverse increment. This **new capability** enhances the robustness of the counter's state management by ensuring proper handling of pending operations and consistency across replicas. The change primarily affects the `counter.ts` module, modifying its op processing and adding a `rollback` method. This feature is thoroughly validated with new unit tests for rollback scenarios, enabled in existing fuzz tests, and integrated into local server stress tests to ensure stability and correctness.
