feat: register Shellphish CRS six pipelines

[occia]

Summary

• Remove the old monolithic crs-shellphish registration
• Add 6 per-pipeline registrations, each pointing to a dedicated branch in shellphish-oss-crs

Pipeline Architecture

The source repo shellphish-oss-crs uses a branch-per-pipeline model:

• The main branch is for development and contains no crs.yaml (gitignored). All code changes go into main.
• Each pipeline branch merges from main and adds its own crs.yaml. This is the only difference from main.
• Each pipeline is a multi-component composition — different pipelines share many of the same build and run modules (e.g., canonical-build, AFL++, coverage tracers).
• See the per-pipeline docs for component details (pipeline architecture, validation results, input/output specification, and inter/intra-component sharing, etc).

All pipelines are tested/testing under the following three C projects and Java projects, including target builds, fuzzing, crash detection, PoV submission, seed sync (sharing and import).

• C: c/sanity-mock-c-delta-01, c/afc-lcms-full-01, c/asc-nginx-delta-01
• JVM: jvm/sanity-mock-java-delta-01, jvm/atlanta-imaging-delta-01, jvm/atlanta-activemq-delta-01

Besides, some integration details are listed at #127 .

[occia]

• Splitted as crs-shellphish-c-fuzzers-aflpp and crs-shellphish-c-fuzzers-libfuzzer
• Fixed Shellphish Jazzer parallel fuzzing bug
• Now redo testing for changed parts (Done)
