chore(agent-config): sync to v1.0.0

[vikshab]

Vendors dpe-agent-config v1.0.0 into .dpe-agent-config/ only.
Nothing outside that directory is touched — .claude/, .codex/, root
lefthook.yml, AGENTS.md, REVIEW.md, CODEOWNERS are yours; this PR never edits them.

Contract check (.dpe-agent-config/verification.sh lint, run on this branch):

Failed — required edits:

FAIL: AGENTS.md missing at root (write it with the agents-md skill)
FAIL: REVIEW.md missing at root (write it with the review-md skill)
FAIL: .claude/CLAUDE.md missing
FAIL: .claude/CLAUDE.md must start with a bare '@../AGENTS.md' line
FAIL: lefthook.yml missing at root
FAIL: the denial log is not ignored; it records commands verbatim (run: .dpe-agent-config/verification.sh init)
FAIL: claude: .claude/settings.json is missing
FAIL: codex: .codex/hooks.json is missing
FAIL: hook registration contract failed (see FAIL lines above)
FAIL: .claude/skills/agents-md/SKILL.md is missing (run: .dpe-agent-config/verification.sh stubs)

FAIL: no CODEOWNERS (run: .dpe-agent-config/verification.sh init)

Codex users: if a hook's registration changed (not just its logic), run
/hooks in your next session and re-trust it, or Codex skips it silently.
A script-only release (most of them) should not trigger this — .codex/hooks.json
is yours and this PR never touches it.

Closing: not onboarding this repo to dpe-agent-config. It is a fork of stackabletech/druid-opa-authorizer that we re-sync from upstream, and the agent-config files would conflict with upstream changes. Tracked in DEN-763.
