Introduce a singleton AMM configuration account, a PDA derived from the
constant "CONFIG" seed, created once via a new `Initialize` instruction.
The config stores the Token Program ID the AMM issues every chained call
to, replacing the previous behavior of trusting the program owner of a
caller-supplied holding.
The config account's existence is the Program's initialization gate: the
chained-call instructions (new_definition, add_liquidity, remove_liquidity,
swap_exact_input, swap_exact_output) now take the config as their first
account, validate it against `compute_config_pda(self_program_id)`, and
read the Token Program ID from it on demand — rejecting calls until the
Program is initialized. Vaults and user holdings are asserted to match the
configured Token Program. sync_reserves is left ungated, as it cannot act
on a pool that could not have existed before initialization.
- amm_core: AmmConfig type, compute_config_pda/_seed, Initialize variant
- amm: initialize.rs + config threading through chained-call instructions
- guest: initialize instruction; config + self_program_id on gated calls
- tests: config fixtures, init-gate unit tests, end-to-end Initialize VM test
Pass `ctx.self_program_id` from `ProgramContext` into `initialize_account`
and `mint`, which now assert that the token definition account is owned by
the token program. This prevents callers from supplying a foreign-owned
account as the definition.

All mutable AMM instructions now require a `deadline: u64` field (Unix
timestamp in milliseconds). Enforcement uses the LEZ-native timestamp
validity window set on ProgramOutput; the runtime rejects the
transaction if the sequencer submission timestamp is at or past the
deadline.
BREAKING CHANGE: AddLiquidity, RemoveLiquidity, SwapExactInput,
SwapExactOutput, and NewDefinition instruction variants now require a
`deadline` field.
Closes#8
Move IDL files to artifacts/ and add a convention-based CI check that
discovers all programs via */methods/guest/src/bin/*.rs and fails if
any program is missing its IDL or has one that is out of date.
