Merge external-dev member baseline; rename to seahaven-org-baseline (#43)
* Parameterize baseline constructs for multi-account reuse

DetectiveControls, FlowLogs, and GovernanceToggles were forked into
seahaven-external-dev-baseline with only physical-name and VPC-sourcing
differences. Prefix/name props let one implementation serve both
accounts; synthesized templates are unchanged (verified: empty cdk diff
against all deployed stacks).

* Absorb external-dev member baseline stack

Moves seahaven-external-dev-baseline's stack in as MemberBaselineStack,
construct ids and physical names byte-identical to the deployed stack
(logical IDs are path-derived; empty cdk diff verified via change set
against 396287094661). Retires the forked repo so member-account
baselines share one drift surface and one dependency pin.

* Rename package to seahaven-org-baseline

Prepares the repo rename: the app now spans the management account and
org member accounts, so 'account-baseline' undersells the scope. README
documents the two-account deploy topology and logical-ID constraints.

* Commit extdev flow-log VPC ids in code, not -c context

Security review SH-ORG-004 (confirmed high): with the ids sourced from
ephemeral cdk context, any context-less deploy silently removes every
flow log in the isolated account. A committed list makes the attachment
set reviewable and immune to a forgotten -c flag. Empty list matches
the deployed stack (zero diff).

* Split CD into per-account deploy jobs

The app now spans two AWS accounts; cdk deploy --all under one role
fails on the other account's stacks (security review IAC-01). Each job
passes explicit stack selectors and its own account's OIDC role via the
new cd-cdk stacks input.

Account detective layer + budget (audit Day 1) (#5)
* Add account detective layer + budget (audit Day 1: H-2/H-3/H-4/M-5/M-10)

Adds to the seahaven-account-baseline stack:
- AWS Config recorder (all + global resources) + delivery channel + role +
  hardened delivery bucket (H-2, CIS 3.3/3.5). Recorder role IAM cross-reviewed.
- GuardDuty detector, us-east-1 (H-3)
- Security Hub with AWS FSBP v1.0.0 + CIS v3.0.0 standards, depends on Config (H-4)
- IAM Access Analyzer, account scope (M-5)
- Monthly cost budget $1,200 with 80/100% actual + 100% forecast alerts to
  adam@seahavenind.com (M-10)

Scope us-east-1 only (all workloads here); multi-region is a follow-up.
The CLI-applied governance toggles (M-6/M-3/M-7/L-8/M-11) are documented
separately in the README runbook.

* Document Day 1 detective layer + CLI governance toggles in README

* Move Config recorder+channel to CLI (L1 stabilization deadlock)

The L1 AWS::Config::ConfigurationRecorder hangs the stack: it never reaches
CREATE_COMPLETE until recording is active (needs a delivery channel), and the
delivery channel cannot be created until the recorder completes — a deadlock
that hung the deploy ~27 min before manual cancel (2026-06-01).

Keep the cross-reviewed recorder role + delivery bucket in IaC; create the
recorder, delivery channel, and start recording via CLI (documented in README).
Security Hub no longer takes a CFN dependency on the recorder; CIS/FSBP controls
evaluate once Config is recording. Verified live: recording=true, SUCCESS.
