feat(init): show AI-generated feature blurbs in setup summary

[betegon]

Summary

Ends the wizard with a "Here's what we set up" two-column table — one row per enabled feature with a sentence specific to the project that was just instrumented. The blurbs come from a new server-side agent that uses the tech-stack description already captured during platform detection (e.g. "Next.js 14 with Drizzle ORM and Cloudflare D1") to produce context-aware copy rather than generic marketing text.

Depends on getsentry/cli-init-api#156 for the server-side agent.

Changes

• WizardSummary and WizardOutput gain an optional featureBlurbs field
• buildSummary() populates it from the workflow output and suppresses the plain "Features" row when blurbs are present (the table makes it redundant)
• Both ink-report.ts (post-dispose chalk output) and logging-ui.ts render the blurbs as a proper two-column table via renderTextTable — same renderer used by sentry issue list / sentry project list, so wrapping and column fitting are handled automatically
• SummaryPanel in ink-app.tsx renders the live Ink variant with flex layout
• Removed "Nice, setup made it through." preamble so the feedback prompt follows the summary directly

Test Plan

• Start bun run dev in cli-init-api, then run MASTRA_API_URL=http://localhost:8787 bun run src/bin.ts init against a real project
• Confirm the blurbs table appears after the key/value fields and before changed files
• Run with --no-tui and confirm the plain-text table renders the same content
• If the blurb agent fails, wizard completes normally with no blurbs shown (try/catch in open-sentry-ui.ts)

Features silently disappear when server returns blurbs with empty strings (src/lib/init/formatters.ts:44)

The plain "Features" field is suppressed whenever output.featureBlurbs is non-empty (line 44), but the blurbs table is only rendered after filtering out null/empty entries. If the server returns any featureBlurbs entries where every blurb is an empty string, the Features row is suppressed yet the blurbs table is also empty — no feature information appears in the summary at all.

Verification

Trace: output.featureBlurbs = [{feature:'errorMonitoring', blurb:''}] → output.featureBlurbs?.length = 1 → !1 = false → guard at line 44 fails → 'Features' field NOT added. Then line 72: blurbsInOrder[0]?.blurb = '' which is falsy → .map() returns null → .filter() produces featureBlurbs = []. Line 88: featureBlurbs.length === 0 → featureBlurbs NOT included in summary. Neither the Features field row nor the featureBlurbs table is rendered. The suppression guard (raw count) and the rendering gate (processed count) are out of sync.
