Implements search functionality for plugin catalogs with configurable search URL and body templates. Adds search icon to browsing header, keyboard entry for queries, and URL encoding for query parameters. Search results use the same item format as browse results. Includes navigation improvements to prevent button press fall-through and proper authentication gating for search requests.
Check that the full token was written to storage. If a short write occurs (e.g., SD card full or I/O fault), remove the truncated token file and return false to prevent pollAuth from reporting success while later loadToken() calls would fail.
Remove the « and » arrow symbols from STR_NEXT_PAGE and STR_PREV_PAGE translation strings across all languages. This simplifies the pagination UI text to just the page navigation labels without directional indicators.
Consolidates repeated IO, HTTP and error-handling logic across plugin/catalog and webserver code. Key changes:
- lib/Epub/Epub.cpp: use extractItemToFile for cover extraction instead of manual write/read.
- src/activities/plugins/PluginCatalogActivity.*: add FsHelpers, pick(), use decodeUriEscapes, introduce fail(), beginLoading(), substitutedHeaders(), openApiClient(), and centralize apiRequest; replace many duplicated header builds and error-state code.
- src/activities/plugins/PluginInfoActivity.cpp: reserve() paragraphs/lines to reduce reallocations.
- src/network/CrossPointWebServer.*: add streamFileToClient() and readJsonBody() to centralize file streaming and JSON body parsing; include ArduinoJson in header.
Reduces duplication, improves robustness and minor perf gains.
Replace hardcoded '> ' prefix with direction markers from translated strings. Change 'Download' button to 'Fetch' for consistency. Add up/down navigation labels when multiple items exist. This allows better localization of navigation UI elements.
## Summary
* **What is the goal of this PR?**
* Prevent reset-only watchdog events from opening the crash-report flow
with an empty panic reason.
* **What changes are included?**
* Record a marker in RTC memory only when panic diagnostics are
captured.
* Continue reporting explicit panics and CPU lockups.
* Require that marker before treating watchdog resets as crashes, and
clear it with the existing panic state.
## Scope Check
CrossPoint is intentionally narrow. See
[SCOPE.md](../blob/master/SCOPE.md) and
[ROADMAP.md](../blob/master/ROADMAP.md).
Please confirm:
- [x] I have read SCOPE.md and ROADMAP.md.
- [x] This PR is **not** a new built-in theme (themes are temporarily
closed pending the move to SD-loaded themes).
- [x] This PR is **not** a new external network connector (sync engine,
cloud storage, remote file access, etc.).
- [x] This PR is **not** an interactive app, writing tool,
RSS/news/browser, media playback, or PDF feature.
- [x] The stock firmware does not already handle this well, **and** no
other popular CrossPoint fork already does
(or, if one does, I explain why CrossPoint still needs it below).
- [x] If this PR touches `freeink-sdk/`, `lib/hal/`, the bootloader,
OTA, or recovery code, I have coordinated with
the relevant maintainer.
**If this PR was opened against the previous (broader) scope and was
already in flight under Phase 0, link the
relevant Discussion or issue so reviewers can see the history.**
## Additional Context
* This is a focused port of CrossInk commit `c96d4275`.
* The change adds 4 bytes of RTC no-init state; it does not affect
storage formats, normal boot routing, or real panic reporting.
* Hardware follow-up: on an X3/X4, confirm a reset-only watchdog boots
normally without an empty crash report, while a genuine panic still
reaches the crash-report screen.

Replace inline findPluginDir with scanPlugins() that returns structured Entry objects containing plugin metadata (plugin.js, device.json, manifest.json markers). This centralizes plugin discovery logic and provides a single source of truth for what constitutes a valid plugin across all roots.
Introduces a DONE state to show download completion message with confirmation before returning to browsing. Refactors layout calculations into a reusable CatLayout structure that uses themed metrics for consistent list geometry across screens. Removes hardcoded visibleRows() method in favor of layout-based page item calculation.
Documents the new plugin discovery system where all plugins appear in Settings → System → Plugins with title/description, and selecting one shows an info screen with README and optional Open action. Also adds guidance on choosing between on-device (device.json) vs browser (plugin.js) implementations with concrete examples for each approach.
Implements a generic on-device catalog browser driven by plugin device.json manifests. Allows SD card plugins to define browsing/downloading behavior via declarative JSON templates (URL/header/body with token/pagination support) without requiring firmware changes. Includes WiFi checking, catalog browsing, and download states.
