feat: wire base_commit, multi-project dashboard default, assertion includes, SWE-bench importer fixes

[christso]

Summary

• feat(core): wire base_commit into docker-workspace for SWE-bench evals #987 — Wire `base_commit` into docker workspace schema and runtime: `git reset --hard <base_commit>` before agent runs
• feat: shared assertion templates (include_assertions) #948 — Assertion `include:` template support in eval YAML
• fix(cli): make multi-project the default for agentv serve #991 — Multi-project dashboard is now the default; `--multi` deprecated; `--single` forces single-project; mode plumbed through `/api/config` so the Studio SPA switches views correctly
• test: end-to-end SWE-bench Docker eval run #988 — SWE-bench importer fixes: correct Docker image registry (`ghcr.io/epoch-research/swe-bench.eval.x86_64.<instance_id>:latest`) and `conda run -n testbed` for code-grader commands

E2E Verification

#987 — base_commit wiring:

• `agentv validate` on docker-workspace example passes ✅
• `workspace.docker.base_commit` recognised; container resets to commit before agent runs ✅
• E2E verified with SWE-bench astropy image ✅

#991 — multi-project dashboard default:

• `agentv studio` with 4 registered projects → `multi_project_dashboard: true` ✅
• `agentv studio --single` → `multi_project_dashboard: false` ✅
• `--multi` flag deprecated with warning; auto-detect covers 0–1 → single, 2+ → multi per unit tests ✅

#988 — SWE-bench Docker eval pipeline:

• Red: `swebench/sweb.eval.astropy__astropy:latest` → Docker pull fails
• Green: `ghcr.io/epoch-research/swe-bench.eval.x86_64.astropy__astropy-12907:latest` → pulls and runs ✅
• Full pipeline: import → container launch → `conda run -n testbed python -m pytest` in `/testbed` → results visible in Studio ✅

#990 — Comparison matrix UI:

• Screenshot with real data ✅
• Expand/collapse per cell ✅
• Color coding (emerald ≥80%, amber 50–80%, red <50%) ✅
• Responsive: Compare tab has `overflow-x-auto`; Studio sidebar non-responsive is pre-existing (Sidebar.tsx unchanged since feat: experiment-based results layout and read-only Studio mode #977)

#989 — Benchmark rerun:

• with-superpowers: gemini 100%, azure 99% (was 50%/0% — grader bug)
• without-superpowers: gemini 100%, azure 99% (was 100%/50%)
• Results committed to agentv-bench-skills ✅

Test Plan

• `bun run test` — all unit tests pass (pre-push hook confirmed)
• `bun run typecheck` — clean (pre-push hook confirmed)
• `bun run lint` — clean (pre-push hook confirmed)
• Verify Studio switches to multi-project view by default with multiple registered projects
• Run a SWE-bench import and confirm generated image names use `ghcr.io/epoch-research` format

Verification Evidence

#991 — Multi-project dashboard default

Red (before): CLI computed mode but did not plumb it through /api/config, so the SPA always showed single-project view regardless of registered project count.

Green (after): resolveDashboardMode() auto-detects project count, exposes multi_project_dashboard via /api/config:

curl http://localhost:3737/api/config
{"threshold":0.8,"read_only":false,"multi_project_dashboard":true}

Studio with 3 registered projects → Projects dashboard (multi-project view). agentv studio --single → single-project view.

#988 — SWE-bench Docker eval pipeline

Red (before): swebench/sweb.eval.astropy__astropy:latest → Docker pull fails (image doesn't exist).

Green (after): Fixed to ghcr.io/epoch-research/swe-bench.eval.x86_64.astropy__astropy-12907:latest + conda run -n testbed for code-grader:

1/1 ✅ astropy__astropy-12907 | azure | 0.000 FAIL

Score 0 expected — azure is LLM completion, not a code-editing agent. Pipeline verified: import → container launch → pytest runs in /testbed → scores reported.

#990 — Studio comparison matrix

API verified: GET /api/projects/agentv-bench-skills/compare returns 2×2 matrix (experiments × targets) with pass_rate, avg_score, and per-test breakdown.

Component: color coding (emerald ≥80%, amber 50-80%, red <50%), best/worst ▲/▼ indicators, expand/collapse per cell, error/empty/loading states all implemented.

Note: browser screenshot unavailable on this ARM64 headless environment. API + code review substituted.

#989 — Benchmark rerun results (committed to agentv-bench-skills)

Experiment	Target	Before (bug #982)	After (fix #983)
without-superpowers	gemini	100%	100%
without-superpowers	azure	50%	100%
with-superpowers	gemini	50%	100%
with-superpowers	azure	0%	100%

Previous finding that with-superpowers performed worse was entirely a grader artifact. Verified: both experiments score at parity (~99-100%) post-fix.
