- Changed hashline format from 4-character to 2-character hex hashes for more compact output.
- Updated `computeLineHash` function to normalize whitespace and removed line number from hash seed for consistency.
- Improved CLI argument parsing with explicit handling of `--help`, `--version`, and subcommand detection.
- Removed `@types/diff` dev dependency as it is no longer needed.
- Created lightweight CLI framework in @oh-my-pi/pi-utils/cli as drop-in replacement for oclif with zero dependencies.

- Changed default root command from 'index' to 'launch' for improved UX.
- Removed @oclif/core and @oclif/plugin-autocomplete dependencies from coding-agent package.
- Deleted custom oclif help renderer (oclif-help.ts) as help rendering is now integrated into the new CLI framework.
- Moved launch command from nested index/index.ts to top-level launch.ts for clearer command structure.
- Extracted stream parsing utilities into reusable functions in pi-utils package (readLines, readJsonl, parseJsonlLenient, readSseJson).
- Replaced manual buffer management with ConcatSink class for efficient stream handling across multiple modules.
- Simplified SSE stream parsing in google-gemini-cli provider by using readSseJson utility instead of manual reader setup.
- Refactored MCP stdio transport to use readLines utility for cleaner line-based stream processing.
- Updated RPC client and mode to use readJsonl utility, removing duplicate JSONL parsing logic.
- Optimized buffer allocations by using allocUnsafe where data is immediately populated and reusing empty buffer instances.
- Extracted custom help class implementation into dedicated oclif-help.ts module to centralize CLI help rendering logic.
- Refactored printHelp() function to delegate detailed help output to oclif's Help class, reducing code duplication and complexity.
- Extracted getExtraHelpText() function to isolate environment variables help section for reuse across help implementations.
- Migrated CLI from custom argument parser to oclif framework for improved command structure and maintainability.
- Reorganized CLI subcommands into individual command files under src/commands/ directory with oclif Command classes.
- Added oclif configuration to package.json with bin name 'omp', commands directory, and autocomplete plugin support.
- Refactored CLI entry point in src/cli.ts to use oclif's run() function with improved error handling.
- Simplified extension flag parsing by directly iterating raw arguments instead of using dynamic flag definitions.
- Updated CHANGELOG.md with comprehensive documentation of new oclif-based CLI commands and migration details.
- Refactored SSE stream parsing to use generic `readSseJson` utility instead of domain-specific handlers across multiple packages.
- Migrated from Node.js Buffer API to Web standard APIs (Uint8Array, TextDecoder, DataView) for cross-platform compatibility.
- Simplified stream transformation pipeline by consolidating multiple stream operations into unified `createTextLineSplitter` utility.
- Refactored `ptree.ts` to remove complex stream pumping infrastructure and simplify stderr handling with direct async iteration.
- Rewrote stream utilities to operate at binary level with byte-level parsing for improved efficiency and reduced string allocations.
- Updated TypeScript configuration to include DOM.AsyncIterable type definitions for async iterable DOM API support.
- Migrated from @types/node to @types/bun across all packages to align with Bun runtime.
- Removed @types/node and bun-types from root and package-specific devDependencies.
- Updated tsconfig.base.json to remove 'node' from types array and 'DOM.AsyncIterable' from lib, keeping only Bun-compatible configurations.
- Simplified ReadableStream type annotation in openai-codex-stream.test.ts by removing explicit Uint8Array generic parameter.
- Replaced nanoid and randomUUID with Snowflake ID generator across codebase for consistent distributed ID generation.
- Created new Snowflake utility module in packages/utils with support for 64-bit distributed ID generation with configurable epoch, machine ID, and sequence numbers.
- Updated session ID format documentation from nanoid to snowflake hex string format (16 hex characters).
- Removed nanoid dependency from package.json as it is now replaced by internal Snowflake implementation.
- Migrated environment variable access from direct process.env to centralized getEnv() utility function across all packages.
- Renamed environment variable prefix from OMP_ to PI_ throughout codebase (e.g., OMP_CODING_AGENT_DIR -> PI_CODING_AGENT_DIR).
- Removed automatic environment variable migration from PI_ to OMP_ prefixes via migrate-env.ts module.
- Removed env setting from configuration schema and applyEnvironmentVariables() method from settings.
- Updated CI/CD build configuration to use PI_COMPILED flag instead of OMP_COMPILED.
