Extend catz.yaml config with a bind-conf section mapping catalog names
to also-notify IP lists. Zones in catalogs with also-notify configured
get an also-notify directive in the generated domains.conf. IPs are
deduplicated and sorted when a zone belongs to multiple catalogs.
Zones without a file= property (e.g. ddns zones) are included in
catalog zone output for secondaries but skipped in domains.conf.
Previously --bind-conf required every zone to have file= set.
Generate a BIND-format domains.conf file alongside catalog zones.
New input properties: file= (zone data path) and dnssec (bare flag).
When --bind-conf is set, every zone must have file= or it errors.
Renames ZoneEntry.File to ZonesFile (input path for error messages)
and adds ZoneFile (BIND file path) and DNSSEC (bool) fields.
Provide catz.yaml.example and zones.txt.example as starting points
for new users. The config follows RFC 9432's recommendation to use
"invalid." for SOA mname/rname. The zones file demonstrates all
supported features: single/multiple catalog assignment, group
property, coo property, and combinations.
Merge readExistingSerial and readExistingContent into a single
readExisting function to eliminate duplicate file I/O. Extract dateBase
helper to deduplicate serial formula between defaultSerial and
bumpSerial. Cache hash results during collision check to avoid
recomputing per member. Normalize error prefixes (remove "error:" from
fmt.Errorf, add uniformly at print sites). Use filepath.Join instead of
manual "/" concatenation. Replace trivial containsStr wrapper with
strings.Contains. Simplify tokenize to a single return. Use writeTestFile
and fixedTime helpers consistently in tests.
Generate RFC 9432 DNS catalog zone files from a declarative input file.
Parses zone-to-catalog assignments with optional group and coo properties,
produces deterministic BIND-format output with automatic SOA serial
management and change detection.
