Add shared oracle_core price-feed types and account-backed validation.
Wire stablecoin to re-export the shared oracle interface and add the mock_oracle program plus IDL artifact.
Update ATA integration tests for the current Transfer instruction shape.
Refs #96
Adds the `open_position` instruction to the Stablecoin Program. The instruction
claims a per-owner `Position` PDA, initializes a collateral vault token holding
via a chained `Token::InitializeAccount` under the vault's PDA authority, and
moves `collateral_amount` from the user's holding into the vault with a chained
`Token::Transfer`. `Position` is persisted with `collateral_amount` and
`debt_amount = 0`; the debt path is deferred to `generate_debt`.
- Add `Position` struct, `OpenPosition` instruction variant, and
`compute_position_pda{,_seed}` / `compute_position_vault_pda{,_seed}` helpers
in `stablecoin_core` with domain-separated PDA seeds.
- Implement `open_position::open_position` mirroring the ATA `create` and AMM
`new_definition` patterns: authorization and uninitialized-state asserts, PDA
verification, and same-transaction chained `InitializeAccount` + `Transfer`.
- Wire the new instruction through the SPEL guest and regenerate the stablecoin
IDL artifact.
- Cover the happy path, all assertion paths, and PDA determinism /
non-collision in 11 new unit tests.
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.

This updates the spel dependency, which introduces a breaking change.
To make reviewing changes easier from other changes, this update comes
in a separate commit.
- Updated `nssa_core` and `spel-framework` dependencies to their respective release candidates in `Cargo.toml` and `Cargo.lock` files for `amm`, `ata`, and `token` modules.
- Enhanced the `new_definition` function in `amm/src/new_definition.rs` to include new claim logic and updated PDA seed calculations.
- Modified tests in `integration_tests/tests/amm.rs`, `integration_tests/tests/ata.rs`, and `integration_tests/tests/token.rs` to accommodate changes in transaction handling and account initialization.
- Refactored account initialization logic in `ata/src/create.rs` and `token/src/initialize.rs` to include authorization claims.
- Updated various functions in `token/src/mint.rs`, `token/src/new_definition.rs`, and `token/src/transfer.rs` to utilize the new claim system for account states.
- Adjusted the IDL generation tool to use the latest version of `spel-framework-core`.
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.
Adds a new `SyncReserves` instruction that updates a pool's recorded
reserves to match the actual vault balances. This allows the pool to
absorb donations (direct token transfers to vaults) without breaking
the invariant — only upward adjustments are permitted; vaults may
not be under-collateralized relative to reserves.
Vault reading helpers (`read_fungible_holding`,
`read_vault_fungible_balances`) are implemented in `amm_core` so they
can be shared across instructions without crossing crate boundaries.
