chore: remove entire.io integration

Reverts 22c442db "Enable entire integration" and drops the accompanying
.gitignore entry:

- .claude/settings.json: removes all seven "entire hooks claude-code ..."
  command hooks (PostToolUse on Task and TodoWrite, PreToolUse on Task,
  SessionEnd, SessionStart, Stop, UserPromptSubmit) and the
  Read(./.entire/metadata/**) deny rule. The file held nothing else, so it
  is deleted rather than left as an empty object.
- .entire/settings.json, .entire/.gitignore: untracked and removed.
- .gitignore: drops the now-pointless .entire entry.

.claude/settings.local.json is untouched; it carries unrelated local
permission settings.
