docs: preserve here-now triggers within index budget

[Navlem]

Summary

• shorten the here-now description from 726 to 47 characters
• move all 15 original quoted trigger phrases into a ## When to Use section
• keep the canonical, compatibility, and Hermes-specific copies aligned

Why

Hermes limits skill descriptions to 60 characters in its prompt index. Longer descriptions render as the first 57 characters plus ....

The current description is 726 characters and appears as:

here.now lets agents publish websites and files to live U...

The body had no ## When to Use section, so the truncated index text was the only trigger guidance available before loading the skill.

Verification

• parsed all three files with Hermes' skill parser
• confirmed each description is 47 characters and is not truncated
• confirmed each file has exactly one ## When to Use section
• confirmed all 15 original quoted trigger phrases remain in the body
• confirmed here-now/SKILL.md and skills/here-now/SKILL.md remain byte-identical
• git diff --check passed
• the four verification endpoints in AGENTS.md returned HTTP 200
