feat(review-graph): add Jev routing comparisons and accounting

[acgetchell]

Review selection currently has no reproducible way to compare its decisions and costs with Jev. Add an opt-in TypeSafe shadow experiment that freezes the source and ordinary selector decisions, asks the pinned Jev model about every catalog leaf, and retains digest-bound inputs, validated results, threshold replays, and per-attempt usage. Ordinary routing, mandatory reviewers, validation, and correctness-evidence gates continue to control normal graph execution.

Add per-command 1Password credential injection, a redacted authentication check, cloud secret setup guidance, and graph-stage accounting that preserves failed or unfinished attempts and explicitly unavailable token/cost measurements. The default experiment runs offline; sending code requires --live, and credentials are never written to experiment artifacts.

Include the tooling refresh to uv 0.12.21, dprint 0.58.0, and rumdl 0.2.78, the Python lockfile updates, and the latest Dependabot rollout evidence. Keep exception tuples in a form supported by the pinned Semgrep parser, using narrow formatter directives.

Validation:

• just ci passed on native macOS with Python 3.14.7: all 805 tests, Python lint/format/type checks, Semgrep scan and fixtures, Markdown, YAML/TOML, GitHub Actions checks, shell checks, and all skill validation. The final run used PYTEST_ADDOPTS='--tb=short -x' to stop on any failure; none occurred.
• Exercised the live routing path on a bounded refactor(changelog)!: adopt pinned shared changelog commands la-stack#261 case after freezing the current selector. At a 0.5 inclusion threshold, Jev selected the same four specialists plus build portability and CLI; the extra specialists added no unique finding in the paired review. This is feasibility evidence, not an accuracy or total-cost claim.
• The Jev request reported 15,127 input tokens, 836 output tokens, 0.264 seconds, and an estimated $0.000635 cost. Codex per-worker token and dollar costs were unavailable; selection-workflow and API timing boundaries differ.
• No API key, private secret reference, or local experiment artifact is included in this PR.

Refs #85. The graph-efficiency work tracked by #87–91 remains separate.

Summary by CodeRabbit

• Documentation
  • Added guidance for checking TypeSafe credentials locally and in cloud environments, including network access and secret configuration.
  • Expanded review workflow guidance for routing experiments, evidence handling, and usage reporting.
• New Features
  • Added a shadow-mode routing comparison that reports decisions and metrics without changing normal review routing.
  • Added usage tracking and reporting for review operations, including partial or unavailable cost measurements.
• Chores
  • Recorded hosted dependency-check status and cooldown details.

Walkthrough

The pull request adds TypeSafe credential-check tooling and documentation, a shadow-mode routing experiment with usage accounting, and tool-version updates with hosted-check evidence.

Changes

TypeSafe credential check

Layer / File(s)	Summary
Credential injection and model check README.md, justfile, scripts/typesafe_check.py, scripts/test_typesafe_check.py	The README and justfile describe local 1Password and cloud credential setup and add command targets. The script validates credentials and model-list responses. Its exception clauses use invalid Python syntax. Tests cover credential validation and endpoint responses.

Review-graph routing pilot

Layer / File(s)	Summary
Routing scope and frozen packet agents/.agents/skills/review-graph/SKILL.md, agents/.agents/skills/review-graph/references/routing-experiment.md, agents/.agents/skills/review-graph/scripts/fixtures/routing_pilot.json, agents/.agents/skills/review-graph/scripts/review_graph_routing_experiment.py, agents/.agents/skills/review-graph/scripts/test_review_graph_routing_experiment.py	The guidance, documentation, and fixture define shadow-mode cases and constraints. The script builds candidate lists, baselines, and digested requests. Tests cover packet preparation and validation.
Usage ledger and runtime accounting agents/.agents/skills/review-graph/SKILL.md, agents/.agents/skills/review-graph/scripts/review_graph_usage.py, agents/.agents/skills/review-graph/scripts/review_graph_runtime.py, agents/.agents/skills/review-graph/scripts/test_review_graph_routing_experiment.py, justfile	The usage script records and validates ledger events and reports grouped totals. The runtime can record operation timing when the ledger is configured. Guidance and tests cover accounting results and incomplete measurements.
Experiment calls and comparison results agents/.agents/skills/review-graph/scripts/review_graph_routing_experiment.py, agents/.agents/skills/review-graph/scripts/test_review_graph_routing_experiment.py	The script validates model responses, records live-call usage, compares probabilities with the frozen baseline, sweeps thresholds, and supports replay. Tests cover live calls, failures, comparisons, and replay.

Tool versions and hosted evidence

Layer / File(s)	Summary
Pinned versions and hosted check pyproject.toml, justfile, .github/DEPENDABOT.md	The uv, dprint, and rumdl pins change. The hosted-check note records a run that found no eligible dependency update and continued to report version 0.12.18; it does not provide approval or merge evidence.

Then logs each call through the night.
Frozen routes stay in their place,
Probabilities join the race.
A tidy ledger marks the way,
And carrots celebrate the day.}

0.12.21 or newer before retaining this pin, so eligible dependency updates can
