Add WithAltDA() option to sysgo orchestrator that starts an in-memory DA server and configures batcher + op-node for AltDA mode with GenericCommitment (no on-chain challenge contract needed). Changes: - New da_server.go: WithAltDA() starts DA server during Deploy phase, appends batcher and L2CL options for AltDA configuration - l2_cl.go: Add AltDA and RollupAltDAConfig fields to L2CLConfig - l2_cl_opnode.go: Apply cfg.AltDA to op-node config; override rollup AltDAConfig when RollupAltDAConfig is set - New altda e2e test: verifies safe head advances and L1 batch txs contain commitments (version 0x01), not raw batch data
The op-succinct validity proposer runs as a subprocess and needs the DA server URL to fetch batch data during AltDA proof generation. Set ALTDA_SERVER_URL in the process environment so it's inherited by spawned subprocesses.

The deploy-oracle step must compile fetch-l2oo-config with the same Cargo features as the proposer binary. Otherwise the vkey commitment derived from the standard range ELF won't match the AltDA range ELF used by the proposer, causing a startup validation failure. Add Features field to L2OOConfigs and WithL2OOFeatures option, and pass features through to `just deploy-oracle <env> <features>`.
The Rust AltDA data source only supports Keccak256 commitments (type 0x00) which are self-verifying inside the zkVM proof. Switch the DA server and rollup config from Generic (0x01) to Keccak256 mode. A dummy DAChallengeAddress is set to satisfy rollup config validation; the challenge contract is never used in e2e tests.
