`idx stocks flow SYMBOL` shows what foreign investors bought and sold of a
stock, session by session, from IDX's own daily trading summary: foreign
buy, sell and net volume, net value at the session's average price, and
the share of value traded outside the regular board, with range totals.
Latest 10 sessions by default (--days, at most 60) or --from/--to. The MCP
server exposes it as get_foreign_flow.
- api/idx: pure parser for GetStockSummary (rows dated another session
are dropped) and a provider over curl-impersonate's profile fallback
with a 30 s limit; Cloudflare passes only some fingerprints.
- flow: each session is cached whole by date, so other stocks' flows for
the same sessions need no request. Weekends are never requested.
- Idx::idx_code is shared by broker and flow for the .JK-only check.

`idx stocks bandar SYMBOL...` reads the broker summary: for the top 1, 3,
5 and 10 brokers per side, buy value minus sell value in basis points of
value traded, with a signal from big accumulation to big distribution on
the headline tier (--top, default 5). Several symbols give a screen ranked
by that figure (at most 100, one request each), which pipes from
`stocks screen`. The MCP server exposes it as analyze_bandar (20 symbols).
- analysis/bandar.rs is pure and versioned (`top_concentration_v1`):
integer basis points, no figure missing counted as zero, buy/sell VWAP
from exact averages, and the brokers on both sides listed because their
gross figures overstate their direction.
- Thresholds (±5%/±15%) follow fzn0x/idx (MIT); docs call them heuristics.
- Invalid input fails a screen at once; other errors fail one symbol and
are warned about on stderr.

Adds a BrokerSummaryProvider capability served by Indo Premier's public
broker summary page: the top 10 buyers and sellers of a stock by lots over
a date range, with totals. No login or key.
- api/ipot: pure parser (decimal scaling of `1.6 M`-style figures), a
client that retries the server's spurious 404s, and a fixture mock.
- broker: Broker::summary/latest over the cache (7 days for closed ranges,
5 minutes for today), range checks, and IDX member names bundled from
GetBrokerCodeList.
- foreign_net_value is null for filtered summaries: the source does not
apply the filters to it.
The endpoint's behavior was first mapped by fzn0x/idx (MIT).

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).
