chore(ai-review): adopt pr-reviewer v1.3.0 native_loop + org-var tokens

[joryirving]

Part of the misospace v1.3.0 fanout — identical to the validated dispatch canary (misospace/dispatch#374).

• Pin v1.2.9 -> v1.3.0 (3479bf5)
• tool_mode plan_execute_loop -> native_loop
• ai_max_tokens -> ${{ vars.AI_MAX_TOKENS || '16000' }} (org-wide variable)
• Thinking-model loop budgets: tool_planning_max_tokens 1500->16000, tool_planning_timeout_sec 45->300, new tool_loop_wall_clock_sec 300

pull_request runs the head workflow, so this PR self-validates.

This PR updates the GitHub Actions AI PR review workflow to adopt pr-reviewer-action v1.3.0 with the new native_loop tool mode and updated token budgets.

Change Summary

Parameter	Before	After
Action version	v1.2.9	v1.3.0 (commit 3479bf5)
tool_mode	plan_execute_loop	native_loop
ai_max_tokens	(not set)	${{ vars.AI_MAX_TOKENS
tool_planning_max_tokens	1500	16000
tool_planning_timeout_sec	45	300
tool_loop_wall_clock_sec	(not set)	300

Standards Compliance

The PR modifies only .github/workflows/ai-pr-review.yaml, a CI infrastructure file. No repository conventions govern GitHub Actions workflow dependency upgrades. The PR follows standard GitHub Actions practices: pinned to a specific commit SHA with a version tag comment for traceability.

Intent Verification

The PR body explicitly enumerates all changes and states this is part of a v1.3.0 fanout, identical to a validated dispatch canary. All diff changes match the stated intent:

• Version bump confirmed (commit SHA 3479bf5)
• tool_mode switch to native_loop confirmed
• ai_max_tokens using org-wide variable confirmed
• Token budget increases (1500→16000, 45s→300s) confirmed
• New tool_loop_wall_clock_sec parameter confirmed

CI Results

All validation gates passed:

• Script test suite: success
• Headless smoke test: success
• macOS validation: success

Evidence Provider Findings

No evidence providers configured for this repository.

Tool Harness Findings

The web fetch to the v1.3.0 release page returned HTML boilerplate but did not surface release notes content. This is a documentation fetch limitation rather than a functional issue; the PR body provides sufficient change enumeration, and the canary reference indicates this version was validated elsewhere.

Unknowns / Needs Verification

• The v1.3.0 release notes content was not accessible via the fetch. However, the PR body enumerates all behavioral changes explicitly, and the PR self-validates by running the head workflow against itself. The referenced canary (misospace/dispatch PR 374) provides additional validation confidence not available in this corpus.

Recommendation

Approve. The changes are internally consistent, all stated parameters are reflected in the diff, CI passes, and the PR follows standard practices for GitHub Actions dependency updates. The self-validation mechanism (pull_request event runs head workflow) provides runtime confirmation.
