fix(daemon): scope dreaming triggers by agent

[NicholaiVogel]

Summary

Fixes the issue #785 agent-scope leak in dreaming triggers and the adjacent hardcoded repair fallbacks.

Changes

• Resolve dream route agent IDs from body agentId / agent_id, query aliases, x-signet-agent-id, then daemon configured fallback.
• Let the dreaming worker run manual triggers against a requested agent instead of only the startup default.
• Make periodic dreaming checks scan registered and data-bearing agents serially.
• Replace hardcoded default fallbacks in the flagged repair endpoints and scope relink-entities memory reads to the selected agent.
• Update API docs for the dream endpoint agent contract.

Closes #785.

Notes

bun run --filter '@signet/daemon' build:types is currently blocked by pre-existing repo-wide TypeScript issues outside this patch, including TS6059 rootDir errors for platform/core/src/migrations/* and existing test casts from Database to ReadDb/WriteDb. The PR has checklist-exception for that local typecheck caveat; no generated declaration artifacts are included.

I did not find a correctness, security, or data-integrity issue worth flagging. The implementation matches the PR description: dream request agent resolution now honors body/query/header/fallback ordering, manual triggers run under the requested agent, periodic checks scan known/data-bearing agents, and the touched repair paths no longer fall back to a hardcoded default.

Confidence: Medium [sufficient_diff_evidence, targeted_context_included, missing_runtime_repro] - The changed route and worker code directly show the new agent resolution path and scoped dreaming calls, and the added tests cover the main body/query/fallback and manual-trigger behavior. I did not have a live daemon trace or DB fixture beyond the included tests, so confidence is medium rather than high.
