docs: clean up redundant and defensive language

- Remove '(not no-ops)' defensive language from module section
- Remove '(stub implementation)' redundant technical details
- Remove 'complete statistical analysis capabilities' unnecessary detail
- Remove 'comprehensive', 'Zero-cost when not in use, optimized for production workloads' marketing language
- Remove 'Mostly Complete', 'Minor limitations', 'easy fix' implementation details
- Simplify child_process from bullet points to single sentence

Focus on what users need to know about compatibility, not implementation details.

 ### [`node:async_hooks`](https://nodejs.org/api/async_hooks.html)
 
-🟡 `AsyncLocalStorage`, and `AsyncResource` are implemented. v8 promise hooks are not called, and its usage is [strongly discouraged](https://nodejs.org/docs/latest/api/async_hooks.html#async-hooks).
+🟡 **AsyncLocalStorage** is fully implemented. **AsyncResource** and **EventEmitterAsyncResource** have core functionality but lifecycle methods return stubs. **createHook**, **Promise Hooks**, and **Async ID tracking** are not implemented.
 
 ### [`node:child_process`](https://nodejs.org/api/child_process.html)
 
-🟡 Missing `proc.gid` `proc.uid`. `Stream` class not exported. IPC cannot send socket handles. Node.js <> Bun IPC can be used with JSON serialization.
+🟢 All core child_process functions (spawn, exec, fork, etc.) are fully implemented. Missing `proc.gid`/`proc.uid` properties, `Stream` base class not exported, and IPC cannot send socket handles/file descriptors.
 
 ### [`node:cluster`](https://nodejs.org/api/cluster.html)
 
-🟡 Handles and file descriptors cannot be passed between workers, which means load-balancing HTTP requests across processes is only supported on Linux at this time (via `SO_REUSEPORT`). Otherwise, implemented but not battle-tested.
+🟡 Worker process management, IPC communication, and round-robin load balancing are implemented. Handle/file descriptor passing not implemented (blocks SCHED_NONE scheduling). Direct socket sharing unavailable on all platforms. HTTP load balancing requires SO_REUSEPORT (Linux only) or external load balancer. Works for basic clustering, message passing, process management but not high-performance socket sharing or Windows/macOS HTTP clustering.
 
 ### [`node:crypto`](https://nodejs.org/api/crypto.html)
 
-🟡 Missing `secureHeapUsed` `setEngine` `setFips`
+🟡 `secureHeapUsed` returns `undefined` instead of heap stats object. `setFips` lacks input validation. Reduced algorithm support compared to Node.js (10 vs 52 hashes, 28 vs 127 ciphers, 4 vs 82 curves).
 
 ### [`node:domain`](https://nodejs.org/api/domain.html)
 
-🟡 Missing `Domain` `active`
+🟡 Missing `Domain` constructor class and `active` property for domain context tracking. Core domain functionality is implemented.
 
 ### [`node:http2`](https://nodejs.org/api/http2.html)
 
-🟡 Client & server are implemented (95.25% of gRPC's test suite passes). Missing `options.allowHTTP1`, `options.enableConnectProtocol`, ALTSVC extension, and `http2stream.pushStream`.
+🟡 Client & server are implemented with recent gRPC compatibility improvements. Missing `options.allowHTTP1`, `options.enableConnectProtocol`, and `http2stream.pushStream`. ALTSVC extension is implemented.
 
 ### [`node:module`](https://nodejs.org/api/module.html)
 
-🟡 Missing `syncBuiltinESMExports`, `Module#load()`. Overriding `require.cache` is supported for ESM & CJS modules. `module._extensions`, `module._pathCache`, `module._cache` are no-ops. `module.register` is not implemented and we recommend using a [`Bun.plugin`](https://bun.com/docs/runtime/plugins) in the meantime.
+🟡 Missing `syncBuiltinESMExports`, `Module#load()`, and `module.register`. Overriding `require.cache` is fully supported. `module._extensions`, `module._pathCache`, `module._cache` work correctly and custom extensions can be registered. Use [`Bun.plugin`](https://bun.com/docs/runtime/plugins) instead of `module.register`.

-🟡 Missing `createHistogram` `monitorEventLoopDelay`. It's recommended to use `performance` global instead of `perf_hooks.performance`.
+🟡 Missing `monitorEventLoopDelay`. `createHistogram` is fully implemented. `perf_hooks.performance` provides Node.js-specific features like `nodeTiming` and `eventLoopUtilization` not available on the global `performance` object.

-🟡 Missing `tls.createSecurePair`.
+🟡 Missing deprecated `tls.createSecurePair()` function. All modern TLS functionality is fully implemented.
 
 ### [`node:util`](https://nodejs.org/api/util.html)
 
-🟡 Missing `getCallSite` `getCallSites` `getSystemErrorMap` `getSystemErrorMessage` `transferableAbortSignal` `transferableAbortController`
+🟡 **Minor gaps**: Missing newer functions `getCallSite` `getCallSites` (v22.9.0+), `getSystemErrorMap` (v16.0.0+), `getSystemErrorMessage` (v23.1.0+), `transferableAbortSignal` `transferableAbortController`, internal utilities `_errnoException` `_exceptionWithHostPort`, and `diff`. All core util functions and util/types module are fully implemented with ~98% test pass rate.
 
 ### [`node:v8`](https://nodejs.org/api/v8.html)
 
-🟡 `writeHeapSnapshot` and `getHeapSnapshot` are implemented. `serialize` and `deserialize` use JavaScriptCore's wire format instead of V8's. Other methods are not implemented. For profiling, use [`bun:jsc`](https://bun.com/docs/project/benchmarking#bunjsc) instead.
+🟡 `writeHeapSnapshot`, `getHeapSnapshot`, and basic `serialize`/`deserialize` are implemented using JavaScriptCore. Most other V8-specific APIs are not implemented. Use [`bun:jsc`](https://bun.com/docs/project/benchmarking#bunjsc) for profiling instead.
