Add inbound filtering of Camel-prefixed headers to prevent external mail headers from injecting internal Camel headers (e.g. CamelFileName). The outbound filter was already in place; this adds the same protection for inbound messages. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add new CML functions for null handling (defaultVal, isEmpty), type coercion (toInteger, toDecimal, toBoolean), date/time (now, nowFmt, formatDate, parseDate), and utilities (uuid, typeOf). Ship a camel.libsonnet standard library with string helpers (capitalize, trim, split, join, contains, startsWith, endsWith, replace, lower, upper), collection helpers (sum, sumBy, first, last, count, distinct, flatMap, sortBy, groupBy, min, max, take, drop, zip), and object helpers (pick, omit, merge, keys, values, entries, fromEntries). Update documentation with full reference for all new functions and the standard library. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Add a `camel transform dataweave` CLI command that converts MuleSoft DataWeave 2.0 scripts into equivalent DataSonnet .ds files, enabling easier migration of Mule integrations to Apache Camel. The transpiler includes: - Hand-written recursive descent parser for DataWeave 2.0 syntax - AST-based conversion to DataSonnet with Camel CML functions - Support for field access, operators, type coercion, null handling, collection operations (map/filter/reduce/flatMap/groupBy/orderBy), string operations, if/else, var/fun declarations - Unsupported constructs flagged with TODO comments - 43 unit tests covering all conversion patterns CLI usage: camel transform dataweave --input flow.dwl --output flow.ds camel transform dataweave --input src/mule/ --output src/resources/ camel transform dataweave -e 'payload.name default "unknown"' Depends on PR #22156 (camel-datasonnet CML enhancements).

Summary
Improve the DataSonnet language integration to make it more ergonomic for Camel users:
cml.defaultVal,cml.isEmpty), type coercion (cml.toInteger,cml.toDecimal,cml.toBoolean), date/time (cml.now,cml.nowFmt,cml.formatDate,cml.parseDate), and utilities (cml.uuid,cml.typeOf)camel.libsonnetstandard library — auto-discovered helper functions for strings (capitalize, trim, split, join, contains, startsWith, endsWith, replace, lower, upper), collections (sum, sumBy, first, last, count, distinct, flatMap, sortBy, groupBy, min, max, take, drop, zip), and objects (pick, omit, merge, keys, values, entries, fromEntries)All new functions are implemented through DataSonnet's existing
