Add immutable read-only Sol Terra Luna trial runner

[stranske]

Summary

• add a Workflows-only, single-arm workflow_dispatch shim backed by an immutable reusable runner
• register exact Sol/Terra/Luna trial profiles while rejecting lifecycle: trial from ordinary Keepalive/agent execution
• enforce high reasoning, read-only permissions, one shared capacity mapping, no runtime fallback, and no auxiliary evaluator
• emit strict quarantine artifacts with replay identity, requested/reported model and reasoning, GitHub run provenance, source SHA plus bounded before/after manifests, and null provider-resolved identity
• pin Codex CLI 0.144.1 and isolate subscription auth without refresh, commits, pushes, comments, PR actions, or target-checkout code execution after auth

Safety contract

• the dispatcher and both registries pin the hardened reusable workflow/helper commit 822e323eefba3edb640e0bd9c922caec6fffee65
• the protected-main dispatcher passes that same SHA as a required runner input; the reusable job verifies it against the target registry before auth
• expected_source_sha must equal current remote main before auth, and every third-party Action in the trial runner is pinned to a full SHA
• this PR must merge with a merge commit, not squash/rebase, so the pinned runner remains in main history
• artifact claims remain instrumentation-only; the local bridge independently authenticates the Actions run/artifact/digest and keeps results quarantined from learning

Verification

• 19 focused Python contract/workflow/docs tests passed
• 35 agent-registry/Keepalive Node tests passed, including ordinary trial-profile rejection
• Ruff, workflow YAML validation, native actionlint, template sync, and strict template completeness passed
• review findings for mutable Actions, ad-hoc install documentation, registry contract drift, normal Keepalive exposure, target-code execution, provenance, reasoning, and source integrity were addressed
• git diff --check passed

Workflow source needed

PR #2749 needs either a linked GitHub issue or one valid non-issue Workflow Source before PR metadata automation can manage it safely.

Please do one of:

• Add <!-- meta:issue:123 --> or a normal Closes #123 / Related to #123 line.
• Check one Workflow Source option in the PR body.
• Add a hidden marker such as <!-- workflow-source:local_request -->, <!-- workflow-source:manual_remote -->, <!-- workflow-source:review_followup -->, <!-- workflow-source:sync_campaign -->, or <!-- workflow-source:dependabot -->.
• Add a workflow source label such as workflow:source-direct-pr, workflow:source-local-request, workflow:source-review-followup, workflow:source-sync, or workflow:no-automation.

Once a valid source is present, this warning will not be reposted.

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in: 35 minutes

Your organization has reached its usage spending cap. Adjust your spending cap in the billing tab.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Pull request overview

This PR adds a new “model-profile trial” execution surface to the Workflows automation stack: a Workflows-only manual workflow_dispatch shim that calls an immutable, read-only reusable runner to execute exactly one Sol/Terra/Luna trial arm and emit a strict quarantine artifact.

Changes:

• Add agents-model-profile-trial.yml (manual shim) plus reusable-model-profile-trial.yml (immutable read-only runner) and a deterministic Python contract helper to validate/emit the quarantine artifact.
• Extend the agent registry (Workflows + consumer template) with a dedicated model_profile_trial_contract and Sol/Terra/Luna trial execution profiles pinned to a specific reusable-workflow SHA.
• Add focused tests and documentation updates to keep workflow inventory, naming, and contract guarantees aligned.
