feat: dfx start --system-canisters for bootstrapping system canisters
This new flag utilizes the built-in system canisters bootstrapping capability provided by PocketIC v10.
dfx nns install is not needed anymore.
When using dfx start --system-canisters, there's no option to specify accounts to have initial balances like you can with dfx nns install --ledger-accounts <account-ids>.
However, the anonymous identity's account comes with an initial balance of 1 Billion ICP. You can transfer some of these ICP tokens to your own account on the ICP ledger. Then convert some ICP into cycles balance on the cycles-ledger.
YOUR_ACCOUNT_ID="$(dfx ledger account-id)"
dfx ledger --identity anonymous transfer --memo 1 --icp 1000000 "$YOUR_ACCOUNT_ID"
dfx cycles convert --amount 100fix: bump svelte dependencies in project templates
Frontend canister
Use BTreeMap instead of HashMap for headers to guarantee deterministic ordering.
Sets the ic_env cookie for html files, which contains the root key and the canister environment variables that are prefixed with PUBLIC_.
Please note that this version of the frontend canister is only compatible with PocketIC v10 and above.

fix: ensure deterministic serialization of tech_stack metadata
The tech_stack metadata was previously defined with HashMap, which resulted in non-deterministic serialization due to its random key ordering.
This has been fixed by replacing it with BTreeMap, which sorts keys and guarantees consistent, deterministic output every time.

fix: deps deploy works with Canister ID out of the ranges of the pocket-ic subnets
The dfx deps deploy command didn't work when the pulled dependency's Canister ID is out of the ranges of the pocket-ic subnets.
The removed replica had one subnet to cover all subnets. While the pocket-ic can dynamically create new subnet when trying to create a canister with specified ID.
