A float was widened to double before encoding, so every float watch,
argument default and result read as the double nearest it: gravity
-9.81 showed as -9.8100004196167, a radius of 0.1 as 0.10000000149011612,
in `get`, `help` and call results alike. Agents read these, and copy
them back into `set` and `call`.
Codec<float> now encodes the shortest decimal that reads back as the
same float (std::to_chars), as a double. Decoding is unchanged, and so
is every value: 0.1 decodes to the float 0.1f came from. A double is
encoded as before.

Crafter.Debug.Core is what the app side and the crafter-debug client
both need, without the session:
- Value: a JSON value with its own parser and printer, so no consumer
interface sees a JSON library. Integers stay integers and whole
doubles stay doubles; NaN and the infinities, which JSON cannot
spell, are written as strings rather than hidden, because a debugger
must not lose a NaN; invalid UTF-8 is replaced so output always
parses. Objects keep insertion order, the order an agent reads.
- Reflect: aggregate members and names through structured-binding
packs and source_location, taken from Crafter.DB, plus scoped-enum
names by probing a range of values. Self-tested with static_asserts
so a compiler that changes function_name()'s shape fails the build.
- Codec<T>: encode, decode and describe for bool, integers, floating
point, strings, enums, optional, vector, array, string-keyed maps,
Value, Required<T> and every aggregate. Decode reports every
problem in a call with its path and, for a typo, the likely intended
name, and never throws: a bad call cannot take an app down, which a
wrongly typed parameter could in 3DForts' hand-written from_json.
- Result, Error and Async: handler results, including ones that take
frames to arrive, so callers need no ready:false polling.
project.cpp now builds Crafter.Debug.Core as its own library, used by
both the app library and the client.
