docs: refresh README for v0.2.4

- Install: add npm/npx (with the pnpm/bun opt-in), platform coverage,
  pin example v0.2.4; Cargo builds from source.
- Runtime helpers as a table, corrected: curl-impersonate is needed for
  IDX ownership discover/import and Yahoo fundamentals
  (IDX_PROVIDER=yahoo), not for stocks history; mutool only for legacy
  PDF reports. Everyday use needs neither.
- Quick start and Features now cover ownership (sync, ticker, entity,
  search, changes, concentration, cross-holders, graph; XLSX source on
  the IDX Data Kepemilikan Saham page) and the full stocks command set
  and providers. Every example was run against v0.2.4.
- Documentation index; script test suites.
- docs: example versions -> v0.2.4; npm publish needs 2FA and a fresh
  version number.

 Downloads the prebuilt `idx` binary for your platform from GitHub Releases,
 verifies it against the release `SHA256SUMS`, and installs it into
 `~/.local/bin` without sudo. Pin a version or change the directory with

-This installs the `idx` binary. `idx-cli` currently requires Rust `1.85+`.
+The npm package downloads the same checksum-verified release binary during

+`bun add --global --trust idx-cli`. See
+[docs/NPM_DISTRIBUTION.md](docs/NPM_DISTRIBUTION.md).
 
-If you use the install script or the Cargo install path directly, some commands also require helper tools at runtime:
-
-- Yahoo-authenticated flows require a `curl_chrome*` binary from `curl-impersonate-chrome` in `PATH`, or `IDX_CURL_IMPERSONATE_BIN` pointing at that binary.
-- Ownership PDF import requires `mutool` from MuPDF in `PATH`.
-
-Install those helpers with your OS package manager, or use the Nix app/package below so they are wrapped automatically.
+Prebuilt binaries cover Linux x64/arm64 (static musl) and macOS arm64/x64.
+On Windows, use WSL.

+Everyday use (`stocks` with the default MSN provider, including history,
+`ownership sync`, and every local ownership query) needs neither.
 
 ## Quick start

 idx stocks quote BBCA,BBRI,BMRI
-idx -o json stocks quote BBCA
 idx stocks history BBCA --period 3mo
-idx config init
-idx cache info

+# Ownership: download the maintained snapshot once, then query locally
+idx ownership sync
+idx ownership ticker BBCA
+idx ownership entity "ANTHONI SALIM"
+idx ownership search salim
+idx ownership changes --from 2026-07-31 --to 2026-08-31

 ## Features
 
-- Provider abstraction (swap data sources behind one interface)
-- Local file cache with TTL
-- Offline mode with stale-cache fallback
-- Human table output and machine-friendly JSON output
+### Stocks
+
+- Quotes, OHLC history, company profile, financial statements, earnings,
+  news, crowd sentiment, and AI insights
+- Analysis: `technical`, `growth`, `valuation`, `risk`, and a combined
+  `fundamental` report; multi-symbol `compare`; MSN `screen`er
+- Providers: MSN is the default for quotes, fundamentals, and screening;
+  Yahoo serves history. Switch with `IDX_PROVIDER=msn|yahoo` and
+  `IDX_HISTORY_PROVIDER=auto|yahoo|msn`
+- Local file cache with TTL, and `--offline` mode with stale-cache fallback
+
+### Ownership (KSEI shareholders above 1%)
+
+- Source: the monthly KSEI holder register ("Pemegang Saham di Atas 1%")
+  published by IDX. Since June 2026 it is an XLSX file on IDX's
+  [Data Kepemilikan Saham](https://www.idx.co.id/id/perusahaan-tercatat/data-kepemilikan-saham/)
+  page; earlier months were PDF announcements
+- `ownership sync` installs a maintained SQLite snapshot (checked daily,
+  currently the latest three months), after which every query runs offline
+- Queries: holders per `ticker`, holdings per `entity`, entity `search`,
+  month-over-month `changes`, `concentration`, `cross-holders`, and an
+  ownership `graph`
+- Self-serve ingest: `ownership discover` finds the latest reports, and
+  `ownership import --url <xlsx-or-pdf>` / `--file` loads them into your
+  local database. See [docs/OWNERSHIP_SYNC.md](docs/OWNERSHIP_SYNC.md)
+
+### Output
+
+- Human-readable tables on stdout, JSON with `-o json`, errors on stderr
