Blog index: front door, weak title, follow path

[superterran]

Three mechanical fixes. All low-risk, high-leverage.

1. Front door - Replaced generic description with specific positioning: who Doug is, what the lens is, no hedging. Cold CTO now knows in 10 seconds if this is worth reading.

2. Weak title - Renamed to a claim: 'Your AI Copilot Doesn't Know What Goes Wrong After Launch.' Matches the register of every other post on the index.

3. Follow path - One line at the bottom: 'Following along: RSS / LinkedIn.' People who liked a post have somewhere to go.

Template/metadata changes only -- no post content changed, no LinkedIn cross-post fires on merge.
