executor-config: bump allowlist to v4; add WRITE_VERBUCKENCE + read_targets classifier + tests

Per COO brief 2026-09-26 §D6 [1]:
- defaults.read_targets: [coreci/company] (every agent inherits read-only AUTO_RUN)
- agent read_targets UNION defaults (append-only, never override)
- WRITE_VERBUCKENCE pre-hoc classifier gate
- T1–T17 test cases; T8/T17 xfail (deny_read_targets punted)

[1] CAIRO task brief — consolidated D1–D6 (per-home mailbox + read_targets parser)

# v4 (2026-09-26):
# - New defaults.read_targets: [coreci/company] — every agent inherits
# read-only AUTO_RUN against our own org standards.
# - Agent read_targets UNION with defaults (append-only).
# - Same append-only rule applied to auto_run_targets for symmetry.
# - Naming convention (v2) preserved.

"""coreci-executor v0.3.0 — governed write rail (Design v1.0 + v0.3 onboarding spec).
"""coreci/executor-config/app/main.py
Tool endpoints (Authorization: Bearer <EXECUTOR_API_KEY> or X-Executor-Key):
POST /submit_request {agent, kind, targets[], content, justification,
credentials: {name: {user, secret}} (optional)}
GET /request_status?request_id=...
GET /health
Web UI (passcode session — EXECUTOR_PASSCODE): / (queue), /ui/request/{id},
/ui/audit, /ui/login, POST /ui/request/{id}/approve|deny.
Policy: allowlist.yaml (fail-closed NEEDS_APPROVAL; AUTO_RUN for agent's own
home-repo packs). PROVISIONING KIND IS NEVER AUTO_RUNNABLE.
Audit: JSONL to logs/ (+ optional Discord webhook). Secrets stay in env.
v0.1.2: CORS for browser-origin schema fetch; Bearer auth support (Open WebUI).
v0.1.3: never-500 login; OpenAPI securitySchemes (Swagger Authorize button).
v0.1.4: allow_headers wildcard — Open WebUI's tool layer sends X-Session-Id.
v0.1.5: allow_origins wildcard — the code sandbox sends Origin: null.
v0.2.0: agent-owned credential relay — credentials ride the request envelope.
v0.3.0: multi-credential named relay (CRED_<NAME>_USER/SECRET env pairs; all
secrets scrubbed from output); 'provisioning' kind = NEEDS_APPROVAL
by construction; audit records credential NAMES only; CEO language.
Allowlist classifier (v4) — see coreci/executor-config/tools/coreci-executor/SPEC.md
