J. Nick Koston c4e1360cdf [api] Check the encoded end against the reserved size under ESPHOME_DEBUG_API
The fixed32 store helper moves to a private section since it neither bounds checks nor
advances the cursor, its comment describes the path each target takes, the generated
file scan flags any ProtoEncode call that does not assign the cursor, and StateWaiter
timeouts can carry a label so gathered waits are told apart.

"""Encode paths at their branch boundaries: zero skipped float, fixed32 state, negative int32,
length prefixes of two varint bytes and two byte field tags."""
