Improve EEPROM naming and scan UX

[Robotmad]

Summary

• improve startup warning reporting and pagination
• • auto-detect blank EEPROM geometry and show manual scan progress
• • stop repeated initialise prompts after the user declines them
• • separate HexManager display name from EEPROM header friendly_name
• • keep HexCurrent in HexManager UI while writing HexCurent into the EEPROM header

Validation

• python -m py_compile sim/apps/HexManager/app.py sim/apps/HexManager/hexpansion_mgr.py sim/apps/HexManager/tests/test_serialise.py sim/apps/HexManager/tests/test_smoke.py
• • deployed to badge hardware on COM7
• • verified on-badge import of the updated HexManager modules
• • manually checked init-decline handling, scan remap, and scan feedback on hardware

Pull request overview

This PR improves HexManager’s startup warning UX and EEPROM scan/init flows, while also separating the HexManager UI display name from the EEPROM header friendly_name (to support “HexCurrent” in the UI while writing “HexCurent” into headers/notifications).

Changes:

• Added message wrapping + pagination for startup warnings (including preserving real import failure reasons).
• Added blank-EEPROM geometry probing + manual “Scan” UX, plus suppression of repeated init prompts after the user declines.
• Introduced vendored EEPROM apps (HexDrive2, HexCurrent) via submodules and updated build/deploy scripts and hexpansions metadata accordingly.

File	Description
tildagon.toml	Bumps app version to 0.4.
app.py	Adds startup warning formatting, message wrapping/pagination, and improved import error reporting.
hexpansion_mgr.py	Adds EEPROM geometry detection, manual scan sub-state, init-decline tracking, and uses friendly_name for EEPROM headers.
hexpansions.json	Adds friendly_name, adds HexCurrent entry, and switches HexDriveV2 to hexdrive2 artifact/version.
README.md	Documents friendly_name semantics and constraints.
EEPROM/hexdrive.py	Introduces _MIN_BADGEOS_VERSION constant and uses it for version gating.
tests/test_smoke.py	Adds tests for warning pagination/import failure reporting and extends app version consistency checks to vendored sources.
tests/test_serialise.py	Adds tests for EEPROM geometry detection, scan UX, friendly_name handling, and init-decline behavior.
dev/download_to_device.py	Adds compilation/deploy of vendored HexDrive2/HexCurrent artifacts.
dev/build_release.py	Adds external module compilation and vendor-dir ignore logic for release packaging.
.gitmodules	Adds vendor submodules (HexDrive2, HexCurrent).
.gitignore	Stops ignoring *.mpy so compiled artifacts can be committed/packaged.
.github/workflows/release.yml	Updates Python setup action (but still needs submodule initialization for new vendor deps).
.gitattributes	Adjusts export-ignore rules and marks .mpy as binary for diffs.
