Metroid Prime Hunters Recomp v0.6.10-alpha

This release is a focused follow-up to v0.6.9-alpha. It keeps the v0.6.9
performance work, bank inventory, and live-shard policy, and fixes several
player-facing launcher/input/diagnostic issues reported after the release.

Fixes

• The launcher's Linear filter toggle now persists between sessions.
• Prime Controls no longer binds gamepad D-pad left/right to touchscreen UI
  helpers by default. That leaves the D-pad available for normal game menu
  navigation on controllers such as the Xbox Elite Series 2 over Bluetooth.
• The Prime Controls Mods page now includes a Restore gamepad defaults action
  that resets gamepad bindings and gamepad aim sensitivity to the shipped
  defaults.
• Performance logs and automatic coverage manifests now share the same
  diagnostics run timestamp when diagnostics are enabled, so files from one
  run are easier to group.
• The framework debug pump shutdown path is guarded against regressing the
  Linux accept() unblock fix.

Packaging

• Windows package version: 0.6.10
• GitHub release tag: v0.6.10-alpha
• Framework pin: aa40b57
• The release package must pass the bank inventory gate and the lean shard
  basic validation before archiving.
• Prebuilt native shards are staged only when their provider identity matches
  the shipped runner, recompiler, headers, compiler policy, and performance
  gate.

Upgrade Notes

Existing live-shard-cache folders remain compatible unless the loader
quarantines a shard for a producer mismatch. The bundled cache is validated
against this exact release runner, and newly discovered runtime pages can still
be compiled by the bundled overlay toolchain.
