updates for v0.3.0 release

[joelee]

[0.3.0] - 2026-04-18

Added

• Multi-turn session memory with local JSON-backed session storage and bounded prompt context
• --session [name], --session-list, --session-show, --session-clear, and --no-session
• session_memory configuration for enabling, scoping, storing, and truncating local session data
• Optional command stdout/stderr capture in session history, with prompt inclusion disabled by default
• session_memory.retention_days for automatic session pruning
• ollama.use_chat_api to switch between Ollama /api/chat and /api/generate

Changed

• Session memory is enabled by default and scoped to the current working directory by default to avoid cross-project leakage
• Planner and unresolved text fallback prompts now receive structured session context when available
• Documentation now reflects the shipped session-store behavior in 0.3.0

Testing

• Added mocked integration coverage for planner transport, unresolved fallback, health checks, and session commands
• Added scripts/coverage-unit.sh for repeatable LLVM-based unit coverage generation
• Added GitHub Actions workflows for unit coverage artifacts and GitHub Pages coverage publishing
• Added Codecov upload support from the unit coverage workflow
• Added documentation for enabling GitHub Pages and browsing published coverage reports
