hermes 15947de51a refactor: split into idx-core library and idx-cli binary workspace
Phase 2 of docs/DESIGN.md, no behavior change:

- crates/idx-core (library): api, analysis, cache, config file handling
  and provider selection, curl_impersonate, error, ownership, runtime,
  plus the shared test fixtures. clap derives are behind an optional
  `clap` feature so the library does not require clap.
- crates/idx-cli (binary `idx`): cli/, output/, and IdxConfig (output
  format and color resolution). Package and binary names are unchanged.
- config.rs is split: file read/write and validation move to core; a
  CLI test keeps core's OUTPUT_VALUES in sync with OutputSetting.
- ownership::db::open_db/db_path drop their unused IdxConfig argument.
- One workspace version; shared dependency versions; no third-party
  version changes in Cargo.lock. LICENSE is symlinked into each crate.
- flake: workspace version, new source paths, and a per-crate package
  check (idx-cli is built from its tarball against packaged idx-core,
  since idx-core is not on crates.io yet). CI cache key, release path
  filter, and the golden whitespace-hook exclusion follow the new layout.

Parity: all 143 golden outputs match byte for byte without
regeneration; 157 core + 17 CLI unit tests (173 before plus the new
OUTPUT_VALUES sync test), 62 CLI tests pass. Live A/B against main:
16/16 stocks cases identical; ownership discover got IDX 403 on both
(exit 4 vs 1 is the phase 1 exit-code change).

idx-cli is a Rust CLI (binary idx) for Indonesian stock market analysis (stocks) and KSEI shareholder ownership (ownership).

Docs:

  • docs/ARCHITECTURE.md: providers, ownership ingest/discovery, error and output contract
  • docs/CONVENTIONS.md: types, naming, testing, and git rules
  • docs/OWNERSHIP_SYNC.md / docs/OWNERSHIP_PUBLISH.md: snapshot consumer contract / maintainer publishing
  • docs/SMOKE.md: Nix checks, test layout, and the live drift check
  • docs/DESIGN.md: idx-core / idx-mcp design and parity gates
  • ROADMAP.md: open work

Rules

  1. Keep data access provider-driven; no ad hoc fetches in cli/.
  2. Keep parse/normalize functions pure.
  3. Tests use fixtures and IDX_USE_MOCK_PROVIDER=1; never hit the live network.
  4. Output contract: tables on stdout, one JSON document with -o json, errors on stderr (JSON-shaped in JSON mode), stdout empty on failure.
  5. Keep ownership queries (releases, ticker, changes, ...) working across every ingest path: XLSX, legacy PDF, archive ZIP/TXT, and snapshot sync.
  6. ownership import --fetch-bing is intentionally unsupported.
  7. Output parity is a contract: never edit golden files to make a change pass. After changing CLI behavior, run the live check and report its summary; report IDX 403s explicitly rather than counting them as passes.

Verify

nix develop --command cargo test <name>  # focused loop
