'Proprietary TBD' is not a valid SPDX expression and Alire 2.x rejects it
(LicenseRef- custom ids are also rejected by the pinned version), aborting
manifest load before build. licenses is optional, so omit it until a license
is chosen. Verified locally with alr 2.0.2 + GNAT 14.2.1: 'alr build' succeeds
and all five test executables pass. (gnat_sockets/spark_lemmas remain declared
but unused -> a non-fatal incomplete-solution warning; build still exits 0.)
Alire 2.x only accepts no/yes for the style_checks build-switch category;
"Max" failed manifest loading so 'alr build' aborted before compiling.
"Yes" enables GNAT style checks (warnings, non-fatal) -- the valid selector
closest to the intended Max. Local gprbuild bypassed alire.toml which is why
this only surfaced in CI (alr build).
- alire.toml rewritten to valid schema ([[depends-on]], real build-switch
values); restrictions moved to gnat.adc
- gnat.adc: project-wide Jorvik profile, No_Exceptions, No_Implicit_Dynamic_Code,
SPARK_Mode On
- mafiabot_core.gpr: source dirs, mains, global config pragmas
- Engine: drop the caller-side precondition race on Transition_State; guard moved
into the protected body with illegal transitions forcing Fault_Halt
- Empty stubs (economy/sockets/exploits): drop Elaborate_Body so they no longer
compile until implemented
