SeedSigner

This commit adds a helper function that decides whether the running software is an official release image. It then uses that helper to hide extra technical details (fork name and commit hash) from the version screen only for official releases. There is no security fix or vulnerability here; it is a UI refinement with tests.

This commit is a routine improvement to how SeedSigner reads version information during automated GitHub testing. It adds a new environment variable SOURCE_SHA so that when outside contributors open pull requests, the displayed commit hash points to the contributor's actual latest commit rather than a temporary merge commit GitHub creates internally. There is no security vulnerability here.

This commit improves how the SeedSigner software detects its own version information when running automated tests in GitHub Actions. It adds new environment variables so that pull request builds correctly show the contributor's branch name and username instead of misleading placeholder values. There is no security vulnerability here; it is a quality-of-life improvement for build metadata.

This commit fixes a small date-parsing bug in the software's version helper. When the code runs in GitHub Actions, Git reports the latest commit time ending in 'Z' (a common UTC notation), but the Python function used to read that date didn't understand 'Z' before Python 3.11. The patch simply replaces 'Z' with '+00:00' so the date parses correctly. It is a compatibility fix, not a security fix.

This commit refactors how SeedSigner determines and records its software version. It removes an environment-variable-based build path and instead reads version info directly from git. The change is mostly cleanup and testing improvements. There is no obvious security vulnerability, but the code still uses shell commands (os.popen) and parses git output, which can be risky if inputs are ever attacker-controlled. Here, the inputs come from the local git state or trusted environment variables, so the practical risk is low.

This commit simplifies a custom camera error exception by removing a hard-coded user-facing error message. The exception still exists and will still be raised; it just no longer automatically includes the text 'Camera error. Check camera connections.' There is no security-relevant change visible in the diff.

This commit is a routine code cleanup and build-system improvement. It renames internal variables (for example, changing 'version_commit_hash' to 'short_commit_hash'), makes the version string consistently include a 'v' prefix, and adds explicit support for detecting the SeedSigner OS build environment. There is no change that affects security or user safety.

This commit simply moves a block of existing code (the git shell command helpers) to a different location in the same file and renames a couple of test methods. No behavior changes, no security fixes, and no new vulnerabilities are introduced.

This commit is purely a code cleanup and test expansion. It renames internal helper methods in the version utility to be clearer (for example, changing `_get_version_name_from_env_var` to `_get_version_name_from_seedsigner_os_env_var`), reorganizes comments, and adds new tests to keep test coverage at 100%. There is no change to user-facing behavior, no fix for a bug, and no security-related change.

This commit restores a helper function that lets the project’s screenshot generator temporarily override version information shown in screenshots. The function is decorated so it cannot run on the actual SeedSigner OS device. It only affects display text used in documentation screenshots, not private keys, seeds, or transaction logic.
