* agent: use primary key index in setRcvServiceAssocs (#1783)
* agent: use primary key index in setRcvServiceAssocs
Previous WHERE rcv_id = ? did not match the (host, port, rcv_id)
primary key prefix and fell back to a table scan via
idx_rcv_queues_client_notice_id. With ~390k rows per queue, each
update in a 1350-row batch scanned the whole table, yielding ~290s
per batch and a multi-hour rcv-services migration.
* agent: pass SMPServer explicitly to setRcvServiceAssocs
Avoid extracting host/port from the first queue inside setRcvServiceAssocs.
The caller already has SMPServer in scope (from tSess) and the call chain
is short, so threading it through is simpler than inspecting the list.
Removes the empty-list guard from setRcvServiceAssocs (it remains in
processRcvServiceAssocs).

* fix tests

* refactor CLI redirect
* xftp-web: fixes and multi-server upload (#1714)
* fix: await sodium.ready in crypto/keys.ts (+ digest.ts StateAddress cast)
* multi-server parallel upload, remove pickRandomServer
* fix worker message race: wait for ready signal before posting messages
* suppress vite build warnings: emptyOutDir, externals, chunkSizeWarningLimit
* fix Haskell web tests: use agent+server API, wrap server in array, suppress debug logs
* remove dead APIs: un-export connectXFTP, delete closeXFTP
* fix TypeScript errors in check:web (#1716)
- client.ts: cast globalThis.process to any for browser tsconfig,
suppress node:http2 import, use any for Buffer/chunks, cast fetch body
- crypto.worker.ts: cast sha512_init() return to StateAddress
* fix: serialize worker message processing to prevent OPFS handle race
async onmessage allows interleaved execution at await points.
When downloadFileRaw fetches chunks from multiple servers in parallel,
concurrent handleDecryptAndStore calls both see downloadWriteHandle
as null and race on createSyncAccessHandle for the same file,
causing intermittent NoModificationAllowedError.
Chain message handlers on a promise queue so each runs to completion
before the next starts.
* xftp-web: prepare for npm publishing (#1715)
* prepare package.json for npm publishing
Remove private flag, add description/license/repository/publishConfig,
rename postinstall to pretest, add prepublishOnly, set files and main.
* stable output filenames in production build
* fix repository url format, expand files array
* embeddable component: scoped CSS, dark mode, i18n, events, share
- worker output to assets/ for single-directory deployment
- scoped all CSS under #app, removed global resets
- dark mode via .dark ancestor class
- progress ring reads colors from CSS custom properties
- i18n via window.__XFTP_I18N__ with t() helper
- configurable mount element via data-xftp-app attribute
- optional hashchange listener (data-no-hashchange)
- completion events: xftp:upload-complete, xftp:download-complete
- enhanced file-too-large error mentioning SimpleX app
- native share button via navigator.share
* deferred init and runtime server configuration
- data-defer-init attribute skips auto-initialization
- window.__XFTP_SERVERS__ overrides baked-in server list
* use relative base path for relocatable build output
* xftp-web: retry resets to default state, use innerHTML for errors
* xftp-web: only enter download mode for valid XFTP URIs in hash
* xftp-web: render UI before WASM is ready
Move sodium.ready await after UI initialization so the upload/download
interface appears instantly. WASM is only needed when user triggers
an actual upload or download. Dispatch xftp:ready event once WASM loads.
* xftp-web: CLS placeholder HTML and embedder CSS selectors
Add placeholder HTML to index.html so the page renders a styled card
before JS executes, preventing layout shift. Use a <template> element
with an inline script to swap to the download placeholder when the URL
hash indicates a file download. Auto-compute CSP SHA-256 hashes for
inline scripts in the vite build plugin.
Change all CSS selectors from #app to :is(#app, [data-xftp-app]) so
styles apply when the widget is embedded with data-xftp-app attribute.
* xftp-web: progress ring overhaul
Rewrite progress ring with smooth lerp animation, green checkmark on
completion, theme reactivity via MutationObserver, and per-phase color
variables (encrypt/upload/download/decrypt).
Show honest per-phase progress: each phase animates 0-100% independently
with a ring color change between phases. Add decrypt progress callback
from the web worker so the decryption phase tracks real chunk processing
instead of showing an indeterminate spinner.
Snap immediately on phase reset (0) and completion (1) to avoid
lingering partial progress. Clean up animation and observers via
destroy() in finally blocks.
* xftp-web: single progress ring for upload, simplify ring color
* xftp-web: single progress ring for download
* feat(xftp-web): granular progress for encrypt/decrypt phases
Add byte-level progress callbacks to encryptFile, decryptChunks,
and sha512Streaming by processing data in 256KB segments. Worker
reports fine-grained progress across all phases (encrypt+hash+write
for upload, read+hash+decrypt for download). Progress ring gains
fillTo method for smooth ease-out animation during minimum display
delays. Encrypt/decrypt phases fill their weighted regions (0-15%
and 85-99%) with real callbacks, with fillTo covering remaining
time when work finishes under the 1s minimum for files >= 100KB.
* rename package
