feat: P2.5-5/6 add --peers/--ca-cert parsing to worker+scheduler with validation
Worker (P2.5-5): - Added parse_peers() static helper to src/worker/src/main.c - Switched getopt to getopt_long to support --peers and --ca-cert long options - When --peers is given: parses into xce_cluster_config_t, calls xce_cluster_config_validate(), logs INFO with candidate count/identity/ca_cert - If validation fails: prints clear error and exits(1) - WARN logged when candidates_count > 3 - Backward compatible: no --peers falls back to existing single-controller path Scheduler (P2.5-6): - Added parse_peers() static helper to src/scheduler/src/main.c - Extended argp struct with --peers (-P) and --ca-cert (-C) options - Same validation/logging pattern as worker - Backward compatible: no --peers falls back to existing single-controller path Tests (new): - src/lib/testsuite/test_cluster_parse.c: 8 unit tests for parse_peers logic (single entry, multiple entries, no-name format, empty/null/missing-port errors, name-stripped correctly, MAX_HA_CANDIDATES cap respected) - Registered in test.c and meson.build - All 8 tests GREEN; 3 pre-existing failures in unrelated GC/CSE tests unchanged
