fix(worker): avoid heartbeat sync storm

[RerankerGuo]

Summary

• ignore Local->Remote-excluded paths when deciding whether the OpenClaw Worker sync loop should run
• stop treating HEARTBEAT.md as a Worker-pushed prompt file so runtime reads/touches do not cause repeated storage uploads
• add a static worker sync regression test and changelog entry

Fixes #949.

Tests

• bash worker/tests/test-worker-sync-excludes.sh
• git diff --check

Temporary dependency

• This branch is temporarily stacked on test: make multi-worker bob setup deterministic #985 (78e9385), whose full CI passed all 10 integration matrices.
• Relative to test: make multi-worker bob setup deterministic #985, this PR retains only its original scoped changes; the shared test fix disappears from the diff after test: make multi-worker bob setup deterministic #985 merges.
• Fresh checks on 1e964c66 passed every build and all 10 integration matrices.

@shiyiyue1102 Hi! Just rebased onto current main (was conflicting after main moved). CI ran but failed on the SHARD_A copaw/hermes flake — same root cause as #972 / #973 / #975 / #976 / #983 / #984 (Manager didn't invoke hiclaw create worker --name bob in the copaw/hermes run; bob worker session was never created).

Good news: PR #985 (test: make multi-worker bob setup deterministic) just turned 18/18 green on its rebase and pinged you this morning as a priority — it replaces the LLM-driven bob creation with a direct hiclaw apply worker --name bob call so the SHARD_A flake cannot reoccur. If #985 lands first, re-running CI on this PR (and the other Tier-3 PRs) should clear them automatically.

This PR's actual change: OpenClaw Worker sync loop excludes HEARTBEAT.md / runtime files from the bulk mirror path so empty cycles no longer trigger. Could you take a look once #985 is in?

Avoiding repeated empty storage mirrors from runtime-touched or excluded files is operationally valuable. The current PR conflicts with main and includes the unrelated multi-worker setup commit, which also appears in several other branches. Please rebase onto the latest main branch, remove the test-06 dependency, and keep only the Worker sync-loop change, its focused regression, and the current changelog entry. Please also make the intended HEARTBEAT.md ownership explicit because changing it from bidirectional to pull-only is a behavioral contract.
