feat(v1): add permissionless timeout fallback for stalled disputes (#166)

[s6pa1rta3n-lab]

Summary

Resolves #166. In Tholos v1, when an assertion enters Status::Disputed, it previously had no mechanism to recover if resolvers became unresponsive, went offline, or failed to reach a majority consensus, leaving both the asserter and disputer bonds locked indefinitely.

This PR introduces a permissionless liveness fallback:

• Configures stalled_dispute_timeout_secs upon contract initialization (bounded between 1 second and MAX_STALLED_DISPUTE_TIMEOUT_SECS of 21 days).
• Exposes admin configuration via set_stalled_dispute_timeout and public read via get_stalled_dispute_timeout.
• Records disputed_at timestamp when an assertion is disputed.
• Implements reclaim_stalled_dispute(id): permissionless fallback callable after disputed_at + timeout < env.ledger().timestamp() that transitions the assertion to Status::Resolved with final_outcome: None and safely refunds both asserter and disputer bonds.
• Follows checks-effects-interactions (storage state updated before token transfers).
• Respects paused contract guardrails and refreshes instance storage TTL.
• Regenerates TypeScript SDK bindings and updates documentation in CONTRACT.md and INTEGRATION.md.
