chore: bump verifiers

[mikasenghaas]

Summary

• advance the deps/verifiers submodule from e2103d6 to d4a2177
• include merged Bash and RLM context compaction from verifiers [Weight Transfer]: Support quantize_in_weight_transfer + EPLB #2454 and feat(orchestrator): drop groups after max_error_reschedule_attempts #2459
• pick up nano-rlm compaction commit 4ef3438 through the default RLM harness pin
• refresh uv.lock for verifiers' aiohttp>=3.14.1 requirement
• migrate three RLM examples to compaction.summarize_at_tokens; use the former range's 98_304 midpoint
• include the optional ACP semantic-edge and shared harness utility changes already on verifiers main

Companions: verifiers #2454, verifiers #2459, and nano-rlm #147.

Breaking

• RLM harness configs must move summarize_at_tokens to compaction.summarize_at_tokens.
• Leave compaction unset to disable proactive and reactive compaction.

Verification

• git diff --check
• uv lock
• uv lock --check
• uv run pytest -q tests/unit/test_configs.py — 133 passed
• git submodule status deps/verifiers — d4a217794fc0bfd70369a8230e56653c193da8ce
• verified that d4a2177 descends from the previous e2103d6 pin

Note

Medium Risk
Submodule bump plus a breaking harness config shape affects all RLM runs still using the old summarize_at_tokens field; example migrations are mechanical but custom configs must be updated.

Overview
Advances the deps/verifiers submodule to pick up merged Bash/RLM context compaction (and related harness defaults), with uv.lock refreshed so aiohttp meets the new >=3.14.1 floor.

Breaking for RLM harness TOML: flat env.agent.harness.summarize_at_tokens is replaced by env.agent.harness.compaction.summarize_at_tokens. The three advanced examples (glm-4.5-air/search, glm-4.5-air/terminal, nemotron-3-super/swe) are updated accordingly—train sources that used a two-threshold list [65536, 131072] now use a single 98304 threshold; eval sources keep 98304 but under the nested compaction key.
