Hadron v0.26.0

Added

• Affected-Only Gate Test Runner Slicing (hadron-forge, hadron-gluon):
  • Implemented AstBlastRadiusAnalyzer::find_affected_crates to detect affected workspace crates from git diffs.
  • Sliced gate test execution in detect_affected_runner and CargoMergeRunner to test strictly changed crate dependency closures for isolated modifications, slashing merge landing cycle times.
• Built-in sccache & mold Compiler Accelerator (hadron-gluon):
  • Implemented CompilerAccelerator with automated discovery and probing for sccache and mold linkers.
  • Integrated automatic environment injection (RUSTC_WRAPPER="sccache" and -fuse-ld=mold) into shared_build_env across all active quark worktrees.
• Dynamic MCP Tool Schema Pruning by Skill (hadron-forge-mcp):
  • Added category-based ToolFilter (Core, Diagnostics, Debugger, Swarm, Nucleus, Profiling, Web) in pruning.rs.
  • Dynamically prunes tool router schemas exposed to ACP Quarks based on the active preon/skill, reducing prompt token tax and latency.
• Nucleus Index Auto-Sharding (hadron-gatekeeper):
  • Implemented automatic index sharding in NucleusIntegrityLinter to partition .hadron/nucleus/index.md by subsystem when nearing the 32 KiB Rule 9 prompt budget limit.
• Semantic 3-Way AST Merge Healer (hadron-forge, hadron-gluon):
  • Enhanced ast_merge and ast_healer with disjoint use reconciliation to resolve non-overlapping Rust import conflicts cleanly without human intervention.
• Inline Diff Steering Directives (hadron-chamber):
  • Added dispatch_steering_directive in DiffSteeringState enabling users to click diff lines and generate targeted steering instructions for active quarks.

Fixed

• ACP Config Options Deserialization (hadron-gluon):
  • Returned updated configOptions dictionary in session/set_config_option response in agy_acp.py, adhering to the ACP SetSessionConfigOptionResponse schema.
  • Added gemini-3.8-flash and gemini-3.8-pro to the fallback model list.
• Affected Test Runner Package Resolution (hadron-forge, hadron-gluon):
  • Mapped crates/hadron-chamber directory to package name hadron in AstBlastRadiusAnalyzer::find_affected_crates and detect_affected_runner, preventing cargo test -p hadron-chamber failure when slicing test suites for chamber changes.
