Phase 1 project revival + PR fixes (#207, #209, #213)

Project infrastructure:
- Replace MIT license with AGPL-3.0 (KSA Technologies, LLC)
- Full README rewrite with badges, compatibility table, token auth docs
- Add CHANGELOG, CONTRIBUTING, DONORS, SECURITY docs
- Add GitHub issue/PR templates, update FUNDING.yml and stale.yml
- Replace external packer repo dispatch with self-contained CI (build.yml)
- Add packaging/DEBIAN/ with postinst/postrm/triggers (no git clone at install)
- Add .perlcriticrc for static analysis
- Add .claude/cos/ ADRs, plans, and runbooks

Bug fixes from community PRs:
- Fix bearer token check in freenas_api_connect: defined() && value instead of
  defined() alone, so truenas_token_auth=0 no longer activates Bearer Token auth (#207)
- Fix LUN 0 falsy bug in ZFSPlugin patch: !$guid -> !defined $guid in both
  zfs_get_lun_number and zfs_get_wwid_number, fixing VMs on LUN 0 for PVE 9 (#209)
- Fix syslog typo "wtih" -> "with" in run_list_extent (#213)

+# This workflow has been superseded by build.yml
+# It previously dispatched to the external freenas-proxmox-packer repository.
+# The build pipeline now lives entirely in build.yml in this repository.
+# This file is kept only to avoid breaking any external references; it does nothing.
