Release v0.2.0

[shelvick]

### Added

• Groves: declarative multi-agent orchestration via GROVE.md manifests. Define topology, bootstrap, governance, confinement, schemas, and spawn contracts in a single file — then run it.
  • Bootstrap: pre-fill task creation forms from file references or inline values.
  • Governance: dual-layer rule enforcement — prompt guidance (LLM reads the rule) AND runtime blocking (code enforces the rule). Supports shell_pattern_block and action_block hard rules.
  • Confinement: per-skill filesystem restrictions enforced at the file_read, file_write, and execute_shell action layer.
  • Schema validation: JSON Schema (Draft 2020-12) validation on file_write actions matching glob path patterns.
  • Spawn contracts: declared parent→child topology edges with auto-injection of skills, profile (with fallback), and constraints.
  • PathSecurity: three-layer defense against path traversal and symlink attacks across all grove resolvers.
• Two example groves shipped: livebench (6-category benchmark) and mmlu-pro (14-subject multiple-choice benchmark).
• Children context enrichment: agents see their children's latest message preview and status directly in the prompt.
• Correction feedback injection: parent feedback is injected into child prompts with lifecycle tracking and root stall notification when children stop progressing.

Fixed

• Per-model consensus queries now run in parallel instead of sequentially.
• Context window overflow from insufficient token safety margins across multiple providers.
• Correction feedback cleared by queued messages arriving during retry.
• Missing :id field in system stall messages crashing the Mailbox UI.
• Empty children signal not injected when no live children exist.
• GPT wait-stall pattern causing agents to idle indefinitely.
• LLM receive timeout too low for slow providers (increased to 300s).

Changed

• Comprehensive Groves documentation added to README.
• DRY refactors: children tracking, skill metadata construction, single-model persist path, PerModelQuery extraction.
