Hadron v0.30.0

Added

• Interactive Event Log Observability & Rich Context Menu (hadron-chamber):
  • Full mouse text selection support for event log row metadata including timestamps ([HH:MM:SS]), author badges (@quark), target indicators (➜ @target), status/kind badges, row indexes, and token spend counters across both compact and expanded rows.
  • Added rich right-click context menu options to Event Log: Copy Event Line ([HH:MM:SS] @author [➜ @target] [kind] body) and Copy Event as JSON (serializing the complete MessageRow model to formatted JSON).
  • Added command event emission for human slash commands in on_input_submit and explicit session reset events ("Archiving session to {session_id}" and "Session reset (archived {session_id})") around /clear operations.
  • Enhanced target legibility in render_row with clear formatting for Kind::Reboot ("force-restart requested for @{to}") and Kind::ModeSet ("mode → {mode} for @{to}" / "(global)"), plus clean slash command formatting without terminal $ prefixes.

Fixed

• Merge Gate Impacted Test Runner Arity (hadron-gluon, hadron-forge):
  • Resolved cargo test multi-symbol positional argument error by strictly constraining test execution commands in detect_affected_runner and compute_impacted_tests to at most one positional filter argument before --, falling back to full-crate testing when multiple files in a crate are modified.
  • Filtered generic test stems ("tests", "test") from Test Impact Analysis (TIA) target symbol extraction.
  • Protected theme.rs token tests with THEME_TEST_MUTEX to prevent race conditions during concurrent test suite execution.

  • Declared rust-version = "1.93" in workspace root Cargo.toml and inherited across all member crates (hadron-chamber, hadron-gluon, hadron-lattice, hadron-forge, hadron-forge-mcp, hadron-gatekeeper), ensuring cargo fails fast with clear errors instead of compile-time E0658 on older toolchains lacking slice_as_array support (resolves GitHub Issue #2).
  • Updated prerequisite documentation in README.md and docs/development/building-from-source.md to reflect Rust 1.93+.

Hadron v0.25.1

Added
