Copy 14 DOT workflow files from the kilroy project and add tests proving
arc can parse them. 11 files parse successfully, exercising features
including subgraphs, fan-out/fan-in, conditional routing, goal gates,
model stylesheets, and large 40+ node workflows.
3 batch test files (batch_*.dot) document a parser gap: arc requires
quoted values for strings with hyphens/dots (e.g., "gpt-5.2") while
kilroy's parser accepts them unquoted.

Aligns with the kilroy implementation of the Attractor spec. A default
of 50 retries is far too aggressive for most workflows.

- Add Provider::ALL constant for iterating all variants in tests
- Add catalog guardrail tests: every provider has models, provider strings
round-trip, as_str round-trips through from_str
- Add arc-agent guardrail tests: every default_model exists in catalog,
profile context_window matches catalog for default models
- Fix context window drift: profiles now look up catalog instead of
hardcoding sizes, with conservative fallbacks for unknown models
- Add #[serde(deny_unknown_fields)] to config structs so typos like
[lmm] instead of [llm] produce parse errors
- Extract DEFAULT_BASE_URL constant in OpenAI adapter

- all_conditional_edges (ERROR): fires when a node has outgoing edges but
all are conditional with no unconditional fallback, preventing silent
fall-through to arbitrary edge selection.
- orphan_custom_outcome (WARNING): fires when outcome-based routing lacks
an unconditional fallback edge, catching typos in outcome values.
- Enhanced condition_syntax rule to also validate via parse_condition(),
catching malformed expressions that pass static checks (e.g. empty key).
- Updated integration test graph to use unconditional fallback edge.

Spawn failures (binary not found) and timeouts are infrastructure issues,
not domain failures. Return them as Err(AttractorError::Handler(...)) so
the engine can distinguish them from script exit-code failures and
potentially retry.

Register Inception Labs' Mercury diffusion LLM as a new provider using
the OpenAI-compatible adapter at api.inceptionlabs.ai. Adds mercury and
mercury-coder to the model catalog and wires up all exhaustive match
arms across arc-llm, arc-agent, and arc-attractor.

Warn when DOT reserved keywords (graph, digraph, subgraph, node, edge,
strict, if) are used as node IDs since they cause silent routing failures.

Three separate binaries are replaced by a single `arc` CLI with subcommands:
arc llm prompt/models, arc agent, arc run, arc validate, arc serve
Extract public CLI modules (arc_llm::cli, arc_agent::cli::AgentArgs/run_with_args)
so the new arc-cli crate can dispatch to each library. Integration tests migrate
to crates/arc-cli/tests/cli.rs.

Per-stage diff.patch files only capture incremental changes between
checkpoints. This adds a comprehensive final.patch covering all changes
from the run's base SHA to the final HEAD, written to logs_root for all
execution environments. Especially important for Daytona where the
sandbox is destroyed after the run.

Git checkpoint commits (stage-level snapshots, diff.patch, GitCheckpoint
events) previously only ran for Local execution. This extends support to
Docker (bind-mount uses host git, same as Local) and Daytona (runs git
commands remotely via exec_command).
- Add GitCheckpointMode enum (Host/Remote) replacing RunConfig.work_dir
- Extract git_checkpoint_host/git_diff_host helpers from inline code
- Add git_checkpoint_remote/git_diff_remote using exec_command
- Enable git_clean check for Docker alongside Local
- Add setup_daytona_git to create run branch in remote sandbox
- Switch Daytona wrap_bash_command from quote-escaping to base64 encoding
(matches TypeScript/Python/Ruby Daytona SDKs, avoids nested quote issues)
- Add e2e tests for both Host mode and Remote mode (Daytona, live-tested)

ULIDs are lexicographically sortable by creation time, making log
directories and run lists naturally ordered without extra metadata.

Make RunConfig.run_id required (String instead of Option<String>) so the
caller always provides the ID. This eliminates the duplicate UUID that
was generated: one in the HTTP server / CLI and a second inside the
engine fallback.
Also fixes a bug in preamble.rs where context key "run_id" was read but
the engine stores it as "internal.run_id", so the run ID always showed
as "unknown" in preambles.
Renames PipelineStarted.id to PipelineStarted.run_id for consistency.

Add git observability to match Kilroy parity: base_sha, run_branch,
worktree_dir on PipelineStarted; GitCheckpoint events with commit SHAs;
final_git_commit_sha on PipelineCompleted/PipelineFailed; run_branch in
manifest.json; final_git_commit_sha in final.json; diff.patch per node;
and git::diff_against helper.

Create a dedicated git branch + worktree per pipeline run (Local env only)
and commit after every node checkpoint. This gives each run an isolated
working directory and a full git trail of changes per stage.
New module: git.rs with ensure_clean, head_sha, create_branch,
add/remove_worktree, and checkpoint_commit (using arc identity).
Engine changes: RunConfig gains run_id and work_dir fields; after each
checkpoint save, a git commit is created in the worktree and the SHA
is stored in checkpoint.git_commit_sha.
CLI changes: for Local execution, the repo cleanliness is verified
before any log files are written, then a worktree is created on branch
arc/run/{uuid}, cwd is switched into it, and cleanup runs after the
engine completes.
Handler changes: run_hook() accepts work_dir so hooks execute in the
worktree.

Rename crate directories, package names, binary names, path
dependencies, use statements, qualified paths, clap command names,
and string literals across the workspace.
