feat(constants): add KnownChains::Gouda; release v0.19.0 (#236)

* feat(constants): add KnownChains::Gouda; wire arms in signet-test-utils

Adds the Gouda variant to KnownChains with FromStr support (case-insensitive).
Gouda is treated as semantically equivalent to Parmigiana (same host chain,
testnet rollup) — all gouda() constructors delegate to parmigiana constants
until a dedicated gouda.rs chain file is written in a later task.

Wires exhaustive match arms in:
- crates/constants/src/types/{host,rollup,environment,mod}.rs
- crates/test-utils/src/specs/{host_spec,ru_spec}.rs

* chore(release): v0.19.0 — adds KnownChains::Gouda

* feat(constants): add chains/gouda.rs with deployed contract addresses

Replaces the parmigiana-delegating placeholders in HostConstants::gouda(),
RollupConstants::gouda(), SignetSystemConstants::gouda(),
SignetConstants::gouda(), and SignetEnvironmentConstants::gouda() with
references to the new chains/gouda module — populated from the gouda
deployment on the parmigiana host (chain id 792669, host deploy height
1143386).

Also adds gouda to the crate's public re-export in lib.rs so the module
is reachable and unreachable_pub lint passes cleanly.

* fix(constants): use parmigiana host genesis timestamp for gouda's HOST_START_TIMESTAMP

Gouda runs on the parmigiana host chain; HOST_START_TIMESTAMP is the
host-chain genesis anchor used for slot-calc math, not the gouda
deploy-on-host timestamp. The deploy-on-host info is tracked separately
via DEPLOY_HEIGHT. Without this fix, anything that derives a slot
calculator from SignetSystemConstants::gouda() would compute slot
numbers offset by ~5 months relative to consumers using parmigiana's
constants, producing inconsistent results for the same host block.

chore: v0.18.0 (#235)

Minor bump for the breaking `BundleKey` change (drop `target_block_number`)
landed in #233. Also re-syncs workspace.dependencies versions with
workspace.package.

feat(tx-cache): change BundleKey cursor to use target_block_number (#231

)

* feat(tx-cache): change BundleKey cursor to use target_block_number

The bundle GET endpoint will be backed by a new block_number_index GSI
that filters bundles to a single target block. The cursor must match
the new GSI key schema, so global_bundle_score_key is replaced with
target_block_number.

Breaking type change. BundleKey is opaque continuation state returned
by the server and round-tripped by clients, so the SDK bump is the
only mechanical fix required.

fix: update for trevm 0.34.2 into_parts() change (#224)

trevm 0.34.2 added a 4th element to `EvmNeedsTx::into_parts()`.

feat: add `Chain::into_parts` and bump workspace to rc.15 (#214)

Add a consuming `into_parts` method to `Chain` so callers can
decompose it into `(Vec<RecoveredBlock>, ExecutionOutcome)` without
cloning. Also adds `docs/` to `.gitignore`.

Closes ENG-2068
