Keystone 3 firmware

This commit adds support for a new Tron transaction format used by the NuFi/Keystone Nexus wallet integration. It changes how the firmware parses, validates, and signs certain Tron QR-code transactions, and it adjusts how unknown TRC-20 token amounts are converted for display. There is no direct evidence in the commit that this fixes a security vulnerability; it reads as a feature/compatability update.

This commit is purely a code-formatting cleanup using rustfmt. It adjusts whitespace, line breaks, and removes blank lines in Tron-related Rust files. The only non-cosmetic-looking change is adding a `fragment_len` parameter to a C-exported signing function, but the diff shows it is simply passed through to an existing encoder call and does not alter security logic.

This commit only adds new automated test cases for the Tron app and removes an unused helper function. It does not change any production behavior, fix a bug, or alter how the device handles real transactions. There is nothing here that would let an attacker steal funds or bypass security.

This commit only reformats Rust source code in the Tron app. It removes blank lines, reorders imports, and adjusts line breaks to match the project's style guide. No program logic, calculations, or security behavior was changed.

This commit adds support for including a text 'memo' field on Tron cryptocurrency swap transactions. The memo is read from an incoming transaction and later copied into the raw transaction data when building a new transaction. There is no obvious security bug in the diff itself, but the change touches how transaction data is parsed and reconstructed, which is a sensitive area in hardware wallet firmware.

This commit fixes the build process for a software simulator used during development. It adds a missing dependency for the Sui cryptocurrency app, wraps a real-device bootloader update check so it is excluded from simulator builds, and provides a simulator-only stub that always returns 'no update needed.' There is no indication this change affects real hardware security or user funds.

This commit simply swaps the on-screen icon for the Keplr wallet. It updates a PNG image, its matching C-language embedded copy, and a hash file used to track assets. There is no code change, no security fix, and no behavior change beyond the new picture.

This commit fixes two minor UI issues. First, it corrects the displayed text for an Avalanche (AVAX) wallet derivation path so the placeholder for the account number is shown inside single quotes (X') instead of outside them, matching the actual BIP-44 path format. Second, it cleans up an incorrect include guard in a header file that was using the wrong macro name and an extra unnecessary #endif. Neither change affects security.

This commit is a pure code-formatting change. It removes an unnecessary line break in a Rust match arm, making the code style consistent with the surrounding code. There is no functional change, no bug fix, and no security relevance.

This commit adds support for the Core Wallet in the Keystone 3 firmware. It mainly expands the number of Avalanche X/P-chain derivation paths from one to ten, updates the Rust SDK dependency, and changes how signing requests extract derivation paths and fingerprints. There is no explicit security fix or vulnerability disclosure in the commit message or diff. The changes are feature-oriented, but they touch sensitive code paths (transaction signing, HD path handling, and master-fingerprint checks), so they warrant careful review.

This commit adds support for the Core Wallet in the Keystone 3 firmware. It mainly expands the number of Avalanche (AVAX) X/P-chain account paths from one to ten, updates the Rust signing code to accept multiple derivation paths from the wallet instead of hardcoding a single one, and bumps the Rust UR registry library version. There is no explicit security fix or vulnerability patch visible in the diff; it reads as a feature/integration change.

This commit is a tiny UI-only change for the NuFi wallet connection screen. It increases the declared size of an image array from 4 to 5 so that a fifth cryptocurrency icon (likely TRON/TRX) can be added. There is no security-relevant change visible in the diff.

This firmware patch changes how TON (The Open Network) wallet public keys are regenerated and how the wallet's 'manage' flag is set. Previously, TON wallets were skipped during normal public-key regeneration and were given a special 'manage' flag. The fix removes those special cases so TON wallets go through the same key-generation path as other wallets, and it prevents public-key switching for TON mnemonics. The change appears to correct a functional bug where TON wallet data could become stale or inconsistent after regenerating or switching accounts, but the commit does not describe it as a security vulnerability.

This commit simply adds TRON (TRX) as a supported coin icon for the NuFi wallet connection screen in the Keystone hardware wallet firmware. It is a routine feature addition with no visible security implications.
