fix(jetbrains): open the worktree row popup only for pull requests

Context

Hovering any worktree row in the JetBrains Agent Manager opened the detail balloon. For a row with no
pull request there is no PR chrome to show — the title line is hidden, the state pill is gone, the
review and CI lines are hidden — so the popup degraded to a bare restatement of the N files +A -D
summary already painted on the row, plus an ahead/behind count against the base branch that is noise
for a local scratch worktree. Passing the pointer down a list of local worktrees trailed one of those
for every row.

The popup is the pull request view, so a pull request is now the bar for opening it.

Implementation

AgentManagerPanel.request() previously opened on any signal — a PR, uncommitted files, or committed
files/ahead/behind — and its KDoc argued explicitly that a PR was not the bar. That decision is
reversed: the gate is now val pull = row.pr ?: return null, and the comment states the new rule.

WorktreeRowPopupBody.update takes a non-null WorktreePrDto rather than falling back to
GhReview.NONE / GhChecksDto(), so the compiler is what rules out a popup without a PR instead of a
runtime branch that could drift back. stats and dirty stay nullable — a PR whose stats have not
polled yet still opens.

Nothing else moves: the row's #number pill, review/CI glyphs and changes summary are untouched, as
is the dwell. A PR-less row still starts the dwell and simply resolves to no request when it elapses.

One consequence worth a reviewer's attention: prs is empty whenever gh is missing,
unauthenticated, or rate-limited, so in those states no row gets a popup even when it does have a PR
upstream. That follows from making PR presence the gate.

How to Test

Manual/local verification

• ./gradlew typecheck from packages/kilo-jetbrains/ — passes, and proves no other caller passes a null pull to the popup body (agent-executed)
• ./gradlew test from packages/kilo-jetbrains/ — full frontend + backend suite passes (agent-executed)
• ./gradlew :frontend:test --tests '*WorktreeRowPopupBodyTest*' — 9 cases pass, including the replaced one (agent-executed)

Reviewer test steps

1. Run the plugin against a repo with several worktrees, at least one with an open PR and one without
2. Hover a worktree row that shows a #number pill — the detail popup still opens beside it with title, state, verdicts and both change counts
3. Hover a worktree row with no #number pill but with local changes — no popup appears, and the row's own N files +A -D summary and its changes-cell tooltip still work
4. Drag the pointer down the list across PR-less rows — no balloon flashes for them

Blocked checks and substitute verification

• Panel-level assertion of the gate is not reachable in this test harness: AgentManagerPanel.place needs a root pane and a laid-out list, and under BasePlatformTestCase the panel is never in a window, so place returns null and no balloon opens for any row — which is why the original feature commit (aebd040a80) shipped with no panel test either. Substitute verification is the compile-time non-null contract plus WorktreeRowPopupBodyTest, where the case asserting the old PR-less behaviour was replaced with a PR row carrying ahead/behind and uncommitted counts so the changes-breakout coverage it provided survives.
