Fix Factory fallback tool use IDs

[gtrrz-victor]

Summary

Fix Factory AI Droid fallback tool_use_id handling so repeated Worker runs with identical inputs do not collide while pre/post task hooks still correlate correctly.

What Changed

• replaced the deterministic fallback-only path with a per-invocation fallback tool_use_id generated during PreToolUse
• added a small Factory-only pending fallback state file under .entire/tmp so PostToolUse can recover and consume the exact ID for the matching Worker invocation when Factory omits tool_use_id
• threaded hook parsing context through the Factory lifecycle parser so the fallback state can be resolved relative to the repo tmp dir
• added focused lifecycle coverage proving repeated identical missing-tool_use_id invocations stay unique, correlate in LIFO order, and clean up temporary state

Verification

• go test ./cmd/entire/cli/agent/factoryaidroid
• mise run test:e2e --agent factoryai-droid TestFactoryTaskHooksDoNotFail

fixes: #917, #930, #938

Pull request overview

This PR hardens Factory AI Droid worker hook parsing so Entire continues running when Droid omits tool_use_id and/or emits tool_response as either an object or a string, and adds regression coverage to prevent reintroducing these failures.

Changes:

• Updated Factory PostToolUse parsing to accept tool_response as raw JSON (object or string) and extract agentId robustly.
• Added a deterministic fallback tool_use_id when Droid omits it.
• Added unit + Factory-only E2E regression tests to ensure hooks do not surface parsing errors during interactive runs.

Follow-up: fix lint and architecture test violations

• Fixed gosec (G304) and wrapcheck lint errors in loadFallbackToolUseState
• Replaced forbidden cli/testutil import in lifecycle_test.go with inline git.PlainInit to satisfy architecture boundary test

Follow-up: bytes-based null check in parseHookToolResponseAgentID

• Replaced string(raw) == "null" with bytes.TrimSpace + bytes.Equal to avoid allocation and handle whitespace-padded JSON
