fix: prism_submit names its workspace default; linked Issues show their GitHub state

[lukemaj]

What: prism_submit now says workspace defaults to this thread's directory, and the Linked PRs and Issues panel shows each linked Issue's current GitHub state (or unknown when it cannot be read) and counts open Issues in its footer.
Why: The description never mentioned the default, so a job ran in the wrong repository (#68); the panel read no Issue state at all and drew every Issue with the open icon, while the footer counted only pull requests (#69).
So what: Review rounds 1 (d6434a1) and 2 (4435f31) by Luna are addressed in 4fce40a; it needs re-review, then the user's merge. The real-thread check of #69 happens after install.

Requirements and who asked: the user (2026-09-29) filed #68 and #69 and asked for both in one PR.
Deleted: making workspace required; a server-side Issue state cache; a manual refresh button; per-Issue issues.detail reads (replaced by one state-only read after review).
Bottleneck: #69's cause: IssueRow hard-coded CircleDotIcon with the success tone and ThreadIssueLink carries no state, so no sync could ever change it; the footer's openCount iterated pull requests only.
Checked myself: ran the targeted tests and typechecks below and read the render and sync code; I did not run the app.

Closes #68
Closes #69

Changes

• apps/server/src/mcp/toolkits/prism/tools.ts: one sentence on the workspace default (description 576 chars, still starts "Use when"); alwaysLoad.test.ts pins it.
• AGENTS.md: run vp as pnpm exec vp where it is not on PATH.
• issues.states RPC (contracts, read scope, handler, IssueService.states): one GraphQL request per host with a resource(url:) alias per Issue selecting only state stateReason; a deleted or invisible Issue returns state: null.
• apps/web: useLinkedIssueStates reads issues.states on the thread's server in chunks of at most 50 Issues (a failed chunk leaves only its own Issues unknown), on mount, every 60 s while shown, and on each pull request sync. Rows draw IssueStateGlyph, a muted circle while pending, and a question glyph for unknown (failed read or no state). The footer adds open and linked Issues to the pull request counts; pending and unknown Issues are not counted open.

Proof (head 4fce40a)

• apps/server: vp test run src/issues/IssueService.test.ts src/issues/gitHubIssues.test.ts src/mcp/alwaysLoad.test.ts: 20 passed. IssueService.states with a fake gh: request shape (state only, one request), null for a missing Issue, IssueOperationError on a gh failure, no request for no Issues.
• packages/client-runtime: vp test run src/state/runtime.test.ts: 29 passed, including a query rereading on its refresh interval while mounted.
• apps/web: vp test run src/components/issues/ThreadLinksPanel.test.tsx src/components/issues/issueLinks.logic.test.ts: 21 passed. The rendered panel shows the expected row icon for pending, failed, missing, open, done and not-planned Issues and the matching footer counts, including an Issue closed after linking; 120 linked Issues read as chunks of 50, 50 and 20.
• tsc --noEmit in apps/server, apps/web, packages/contracts, packages/client-runtime: 0 errors.
• vp lint on the touched files and directories: no findings.

Not covered

• Behaviour in a real thread (after install, per Linked Issues panel keeps showing closed Issues as open #69's required proof).
• The footer only renders when the thread has at least one linked pull request (unchanged).
• A failed chunk read marks that chunk's Issues unknown until its next successful read.

Independent review (Codex gpt-6-luna, three rounds): round 1 on d6434a1 and round 2 on 4435f31 requested changes (failed reads counted as open, no refresh without PR sync, full detail read per Issue; then the 50-Issue cap and no rendered test). All fixed. Round 3 on exact head 4fce40a: APPROVE, no new defect; pnpm exec vp test run src/components/issues/issueLinks.logic.test.ts src/components/issues/ThreadLinksPanel.test.tsx passed (2 files, 21 tests).
