Bumps `typescript` to ^6.0.3 in both the `clients/js` and
`clients/js-legacy` packages and adjusts their tsconfigs for TS6. The
shared workspace `pnpm-lock.yaml` is re-resolved onto typescript@6.0.3.
clients/js (tsc -> tsc-cjs build):
- add "ignoreDeprecations": "6.0" to tsconfig-base.json — both "baseUrl"
(TS5101) and the node10/"node" module resolution (TS5107) are
deprecated in TS6. "rootDir" and "types" are already set, so no other
changes were needed.
clients/js-legacy (tsup + tsc declaration emit):
- add "ignoreDeprecations": "6.0" and "rootDir": "./src" to
tsconfig.declarations.json — TS6 deprecates the inherited node10
module resolution (TS5107) and requires an explicit rootDir when
emitting declarations to outDir (TS5011). Setting rootDir also
corrects the declaration layout to dist/types/index.d.ts, matching
the package's "types" field.
- add "types": ["node"] to tsconfig.json — under TS6 the declaration
build no longer auto-resolves @types/node for the `import { Buffer }
from 'buffer'` statements (TS2591); this mirrors the sibling
clients/js base config which already sets it.
Verified locally with typescript@6.0.3:
- clients/js: `pnpm build`, `pnpm test` (tsc typecheck), `pnpm lint`,
`pnpm format` all pass.
- clients/js-legacy: `pnpm build` (tsup + tsc declarations), `pnpm lint`,
`pnpm format` all pass.
The clients/js-legacy `ava` suite drives litesvm; its compiled test
output is byte-identical before and after this change, and the same
subset of stake-heavy tests hits a litesvm native std::bad_alloc under
both typescript@5.9.3 and @6.0.3, so behavior is unchanged.

Upgrades both JS clients —
clients/jsandclients/js-legacy— totypescript@^6.0.3. Because the two packages share a single workspace-rootpnpm-lock.yaml, they're upgraded together in one PR (splitting them would mean conflicting edits to the same lockfile).Changes
