docs: update CHANGELOG, CONTRIBUTORS, and fix DI snippet for module guides (#4848)

- Add CHANGELOG.md [Unreleased] entry for the three new module guides
- Add CONTRIBUTORS.md entry for HAL9000 authoring the module guides
- Fix InvariantReconciliationActor DI container snippet in
  invariant-reconciliation.md: replace incorrect event_bus/audit_service
  params with the actual constructor params (invariant_service,
  decision_service) as defined in src/cleveragents/actor/reconciliation.py

 ## [Unreleased]
+- **docs: module guides for Sandbox & Checkpoint, Correction Attempts, and Invariant Reconciliation** (#4848): Added three comprehensive module guides covering purpose, core classes, lifecycle diagrams, exception hierarchies, CLI usage, and ADR links for `SandboxManager`, `CorrectionAttemptManager`, and `InvariantReconciliationActor`. Includes security callouts for `NoSandbox` bypass (permanent writes, no rollback), `guidance` prompt-injection risk, `archived_artifacts_path` provenance, and `non_overridable` global invariant access control.
 - **feat(context): PriorityContextStrategy** (#9997 / PR #10772): Implements a priority-based context strategy that ranks context fragments by configurable priority scores — default role-based rules (system > tool > user > assistant), exponential recency decay (7-day half-life), and explicit priority tag boost. Supports custom scoring function injection and custom PriorityRule list injection. Registered in the ACMS pipeline under key `priority_context`. `PriorityRule` uses Pydantic `BaseModel` for architecture conformance. Includes 18 BDD scenarios covering all acceptance criteria.
 - **docs(timeline): verify timeline status for 2026-04-16 Cycle 2** (#8519): Updated `docs/timeline.md` with Days 104-106 Cycle 2 milestone snapshot. No changes detected since Cycle 1. All M3-M7 milestones remain overdue. Timeline verification performed by AUTO-TIME-3 supervisor agent. Refs #8519.
 - **fix(cli/plan): plan correct JSON output envelope fix and BDD test coverage** (#8584 / PR #8662): Restructured `agents plan correct --format json` output to nest correction fields under `data.correction` (e.g., `data.correction.mode`) and populate the spec-required CLI envelope with `command="plan correct"`, `status`, `exit_code`, `timing`, and `messages` fields. Added three BDD scenarios in `features/tdd_plan_correct_json_output.feature` validating the envelope structure for both revert and append modes.
