feat(remote_agent): add adjacent_possible idea generation telemetry

[PiyushDatta]

Summary

• Apply WorkerPal completion f90d8a29-5831-4a9f-affc-950358deaadd to main_agents.
• Integrate commit b953c8243dd5c9009472b51b9b6868e4d32d6bd2 from refs/pushpals/agent/workerpal-281a46c7/f90d8a29-5831-4a9f-affc-950358deaadd.
• Worker workerpal-281a46c7 reported: Executed task and modified 2 file(s)
• Canonical task request: Implement and export adjacent_possible logic in apps/remotebuddy/src/autonomous_engine.ts so it recombines prior successful motifs with current bottleneck data, emits structured telemetry for idea generation steps, and includes guardrail...

Motivation / Context

• Preserve and review autonomous worker output before final merge to base branch.
• Keep integration branch current with queued worker completions.

Planned Scope

• apps/remotebuddy/src/autonomous_engine.ts

Planned Validation

• Planned: bun run test:root

Changes

• Updated apps/remotebuddy/src/autonomous_engine.ts

Testing / Validation

• Planned: bun run test:root
• Worker completion summary did not include explicit command pass/fail output.

Impact / Risk

• Risk level: medium (automated worker-generated change; maintainer review required).
• No secrets or credentials are expected in this PR body.

SourceControlManager Note

• Use this worker-provided PR title/body when creating the integration PR.
• Suggested title: fix(repo): Implement and export adjacent_possible logic in apps/remotebuddy/src/autonomous_engine.ts so ...

ReviewAgent: Changes Approved (score 8.3/10)

Verdict: The implementation is generally solid and well-tested for core paths, but it includes unreachable guardrail logic and misses a few high-value negative tests for production confidence.
Threshold: 8.1/10
Why this passed: Score 8.3/10 is >= 8.1/10.

Potential Improvements:

• Unreachable branch in adjacent_possible: duplicate_pair can never trigger because motifs and gaps are deduplicated by ID before pair generation, so each (motifId, gapId) pair is constructed at most once; this is dead code that adds misleading telemetry paths.
• Test coverage misses key failure paths introduced by the new logic, specifically unknown_motif, candidate_shape_incomplete, and maxIdeas <= 0 (max_ideas_disabled) telemetry behavior; these are explicit branches in the function and should be asserted to prevent regressions.

This PR met the configured review threshold and is approved for automated merge.
