…ceiling check to prevent multi-read overflows

…text window formulas

… limits

- runtime-flags: enable background subagents by default (Config.succeed(true))
- task: add wait_for param for explicit fan-out/join; LLM can fire N background
  tasks then call task with wait_for:[id1,id2] to collect all results in one step
- task: collect all text parts from subagent result (not just last) with streaming
  accumulator pattern
- task: compress task results via compressTaskResult before injecting into parent
  context — head/tail extraction keeps result within 8% of context window
- result-compressor: new pure-function compressor using dynamic context ratio;
  no hardcoded token values
- compaction: all three static constants (DEFAULT_KEEP_TOKENS, TOOL_OUTPUT_MAX_CHARS,
  SUMMARY_OUTPUT_TOKENS) replaced with dynamic formulas based on model context window

…compression service

- ResultCompressor.Service: implements live LLM stream compression using LLM.Service.stream()
- Uses COMPRESS_SYSTEM prompt to generate dense, structured Markdown summaries preserving exact file paths, symbol names, values, decisions, and error logs
- Dynamically derives max tokens (8% context budget) and safety fallback thresholds
- Registered ResultCompressor.node in ToolRegistry and Effect application graph
