README screenshots: real app captures replace the placeholders

[LXBStudioLLC]

Closes #16. This was the last item before flipping the repo public.

What changed

• The three "screenshot coming soon" cards in the README are now real captures of the v1.0.2 build:
  • assets/ghost-score.png: the Ghost Risk panel on the Apply view, a HIGH band with its evidence lines.
  • assets/find-jobs.png: Find Jobs results with a risk band on every posting, including one flagged HIGH and one that stays OK while still showing its evidence.
  • assets/apply-copilot.png: the Apply view stopped at the Confirm / Cancel gate.
• Removed the stale swap-this-image comments and the "coming soon" captions.
• The release badge now reads the latest release from GitHub instead of a hardcoded v1.0.1. It starts rendering once the repo is public.
• One real fix the screenshots exposed: the Operation Mode dropdown on the Apply view used the default WPF combo chrome, a light bar with light text on it. CyberComboBox now bases on the HandyControl dark template the app already ships.

About the data in the shots

The screenshots are the real app, staged with fictional demo data instead of live results:

• No real company appears next to a risk band. Fictional names only (Contoso, Northwind, Woodgrove, Tailspin, Fabrikam, Proseware).
• No personal data. Nothing from the vault or a real profile is in frame.
• Every state shown is one the shipping scorer can produce. The HIGH 72 in Find Jobs matches the scam signal math (0.85 score x 0.85 confidence), the HIGH 87 on the Apply view matches two converging strong tells (0.95 x 0.92 after the convergence boost), and the stale reposted listing shows OK with evidence lines because a single probabilistic signal stays Neutral by design. No Elevated badge appears anywhere, since that band needs two probabilistic signals and only Posting Age ships today, matching the README's own scoring table.
• Each caption states that the data is fictional.

Staging was a temporary env-gated hook on this machine only; it is not part of the diff. The diff ships the images, the README text, and the combo style fix.

Verified

• dotnet build -c Release clean.
• App launched from the Release build for each capture; the dropdown fix is visible in the ghost and apply shots.
• README greps clean for em-dashes.
