docs: fix "stop button" → "pause button" in Agents docs

[selfcontained]

Summary

• The in-app Agents docs "Starting and stopping" section said "Press the stop button to terminate it." The UI consistently uses Pause terminology — the button icon is Pause, the aria-label says "Pause", the confirmation dialog title says "Pause Agent", and the dialog body says "The session will be paused. Resume it later to continue where you left off."
• Updated the docs to say "Press the pause button to stop it — a confirmation dialog appears first, and you can resume the session later." Removed the misleading "terminate" wording.

Audit scope

Deep-dive of the full Agents docs section (docs-sections/agents.tsx) against agent-card.tsx, create-agent-dialog.tsx, create-agent-worktree-section.tsx, use-create-agent-form.ts, agent-sidebar.tsx, center-pane-tab-bar.tsx, stop-agent-dialog.tsx, diff-stat-badge.tsx, and agent-event-utils.ts.

Verified accurate (no changes needed):

• Creating an agent: all 6 form fields, type list, "Create with context" flow
• Setup phases: all 4 phase labels match
• Status indicators: all 4 color mappings, collapsed vs expanded content
• Sidebar badges: Attention, Job, Update — all 3 match
• Reordering: drag-and-drop + Alt+↑/↓ keyboard shortcut
• Sessions are persistent: tmux claim
• Agent details: worktree vs non-worktree metadata, diff-stats badge, access mode badge, feedback panel, persona launcher, persona agent display
• Diff-stats badge: hidden when zero, flash on change, stale opacity, click-to-refresh, tooltip file count
• Changes tab, Split pane, Tmux scrollback, Quick Phrases, Renaming, Archiving, Orchestration — all verified

Deferred to next run

Next focus: audit docs-pane Repo Tools section against apps/server/src/shared/mcp/server.ts AGENT_TOOLS/JOB_TOOLS/PERSONA_TOOLS sets, and verify each repo tool's description matches the actual tool handler behavior.
