- Added `initialize_redemption_controller` and `update_redemption_controller` functions to manage redemption rate feedback.
- Introduced `RedemptionController` struct to maintain state for redemption rates.
- Updated `Cargo.toml` and `Cargo.lock` to include `twap_oracle_core` dependency.
- Modified integration tests to cover new redemption controller functionality.
Replace the hardcoded numeric byte-stream seeds ([0; 32], [1; 32], ...)
used for domain separation in PDA derivation with descriptive byte-string
constants, mirroring the AMM config account's existing b"CONFIG" seed.
amm: [0; 32] -> b"LIQUIDITY_TOKEN"
[1; 32] -> b"LP_LOCK_HOLDING"
stablecoin: [0; 32] -> b"POSITION"
[1; 32] -> b"POSITION_VAULT"
twap_oracle: [2; 32] -> b"PRICE_OBSERVATIONS"
[3; 32] -> b"ORACLE_PRICE_ACCOUNT"
[4; 32] -> b"CURRENT_TICK_ACCOUNT"
Since the seeds are now variable-length, each compute_*_pda_seed function
builds its hash input with a Vec and extend_from_slice instead of a
fixed-size buffer with offset writes.
Closes#146
