feat(miner-manage-ui): manage-phase dashboard panel for run portfolio

[JSONbored]

A basic textual panel for managed PRs already exists: manage-status.js (#2325/#3070) implements collectManageStatus (manage-status.js:59-107, joining the portfolio queue and event ledger), renderManageStatusTable (manage-status.js:114-141), and a wired CLI command — gittensory-miner manage status [--json] is dispatched in bin/gittensory-miner.js (cliArgs[0] === "manage" && cliArgs[1] === "status"). So this issue is not "build a panel from nothing"; it's narrower than the title suggests once the existing coverage is accounted for.

Two gaps remain. First, collectManageStatus is PR-scoped only — it never reads run-state.js, so there's no view of a repo's own discover→plan→prepare lifecycle (idle/discovering/planning/preparing) alongside its tracked PRs; a "run portfolio" panel implies both. Second, an actual GUI dashboard surface doesn't exist in this repo yet: apps/gittensory-miner-ui/ is explicitly Phase 6 scope in the same roadmap tracker this issue comes from (tracker #2353: feat(miner-ui): scaffold apps/gittensory-miner-ui/ dashboard shell), and Phase 6 has not been released as filed issues yet (only Phase 4 is being released now) — so building a real dashboard app here would be building ahead of its own scaffold.

Deliverables

• Extend collectManageStatus (or add a sibling aggregator) to also read run-state.js's per-repo state and fold it into the panel — a "run portfolio" row per tracked repo showing its current discover/plan/prepare state alongside its managed PR rows, not PRs alone
• Extend renderManageStatusTable/add a new render function for the combined view; keep the existing manage status output and --json shape backward compatible (additive fields, not a breaking rename)
• This lands as a CLI-only enrichment of the existing gittensory-miner manage status command for now — do not scaffold apps/gittensory-miner-ui/ here; note the dependency on the (not-yet-filed) Phase 6 dashboard-shell item for an eventual GUI surface
• Unit tests extending test/unit/miner-manage-status.test.ts's existing style for the run-state-inclusive aggregation and render output
• Update packages/gittensory-miner/README.md's ## Commands section, which currently doesn't list manage status/manage poll at all despite both being wired in bin/gittensory-miner.js
