v0.10.0 — Agent architecture decoupling and dialogue-state tracking

Added

• Dialogue-state tracking wired in: the previously uncompiled dialogue-state feature is now live — DialogueStateStore trait defined and included in the StateStore facade, dialogue_states table created by migration, runtime rebuild/record functions compiled, and part_13_dialogue_state integration tests included in the suite.
• Specialist prompt overhaul: specialists share a common _executor_base.md core with per-kind sections; spawn_agent descriptions nudge delegation when work fits a specialist.

Changed

• Agent internals decoupled (no user-facing behavior change) — completion of the architecture campaign started in v0.9.0:
  • The ~60 loose mutable variables in the agent loop now live in 8 per-concern state structs (StallTracker, FailureLedger, RecoveryState, BudgetTracker, EvidenceLedger, ReflectionState, PendingDirectives, LoopCounters) composed in a TurnState, with per-phase projections.
  • All nine loop phases (bootstrap, orchestration, message build, LLM, response, completion, stopping, tool prelude, tool execution) are free functions with explicit Ctx inputs and Outcome results — no more extension-method sprawl on the Agent struct (31 impl Agent blocks reduced to 13, each justified).
  • runtime/history.rs (4,117 lines) split into followup, completion_contract, turn_context, project_scope, and notes modules; agent/mod.rs shrunk from 4,233 to ~800 lines; no file in src/agent/ exceeds ~2,000 lines.
  • Outer ring: deferred cycle-breaking wiring consolidated into startup/wiring.rs; new ApprovalBroker type replaces the raw approval channel sender threaded through 21 files; Telegram bootstrap-signing and approval rendering extracted from telegram.rs; six tools narrowed from the full StateStore facade to the specific store sub-trait they use.
  • Verified behavior-preserving by characterization tests (stall, force-text, completion blocking, truncation recovery, background ack) and an identical 2,294-test green suite at every slice.
