…wer temperature

Add "How to act" section to main agent profile instructing the LLM to

feat: use edge glow gradient for device control border overlay

fix: update release skill to copy signing files from parent directory

refactor: collapse all database migrations and reset to version 1

No users yet, so remove all incremental migrations and let Room
recreate tables from current entity definitions on fresh install.

feat: add self-knowledge to main agent profile and about-oneclaw skill

Give the agent awareness of its own identity, capabilities, and source
code. The main profile now includes an identity block, capabilities
list, and two-step GitHub source fetching instructions (tree API for
path discovery, then raw content fetch). The new /about-oneclaw skill
provides comprehensive architecture docs, full tool inventory, and
entry-point file references for deep exploration.
