🎨 Palette: [UX improvement] Add 'or try an example' to optimizer page

[madara88645]

💡 What:
Added an "or try an example" button to the empty state of the Optimizer page text area that populates the field with a sample prompt when clicked.

🎯 Why:
This addresses the "blank canvas" problem by providing users with immediate context and an example of the kind of input the optimizer expects, reducing friction and making it easier to try out the tool. It also brings the Optimizer page's UX inline with the other generative pages (Compiler, Benchmark, etc.) which already had this feature.

📸 Before/After:
Before: The text area was completely empty with only placeholder text, requiring the user to come up with their own prompt to test the tool.
After: The empty state now features a small, accessible "or try an example" button that immediately fills the text area with a good example prompt.

♿ Accessibility:
The new button includes focus-visible classes (focus-visible:ring-1 focus-visible:ring-emerald-500) to ensure strong keyboard accessibility, matching the persona's requirements for all interactive elements.

PR risk assessment

Risk level: Low

Code review: Not required (automation approval)

Evidence (diff-only)

Area	Change
web/app/optimizer/page.tsx	+13 lines: empty-state "or try an example" button that pre-fills the left-side prompt when input is empty
.jules/palette.md	+3 lines: internal Jules learning journal entry (not production model instructions)

Why Low (not Medium+):

• Blast radius: Single page, client-only setInput(...) — no API, auth, compiler, export, or infra changes
• Complexity: Mirrors the existing pattern on Compiler, Benchmark, Agent Generator, and Skills Generator pages
• Surface area: Minor UX parity for the Optimizer empty state; no shared libraries or core services touched
• Security / ops: No new trust boundaries, secrets, or data paths

Overrides checked:

• Not a production prompt / system-instruction change (.jules/palette.md is a team learning journal per repo docs)
• No CODEOWNERS file in this repository

Actions taken

• Reviewers: None added (Low risk; Copilot already requested by GitHub)
• Approval: Approved by automation (Low risk, no prior approval on this PR)
