Micro-optimisation on sourcemap extraction, no behaviour change but twice the speed.

I originally discovered this because an application hit V8's TooMuchRegexpCode condition and then was using a non-optimised version of this regex. That condition was removed in new V8 versions though: https://chromium-review.googlesource.com/c/v8/v8/+/7743527

fix(deps): hold Vite at 8.3.4 until Vitest fixes vitest#11682
abd7c3b 
CI failed after every test passed: an unhandled "code.charCodeAt is not a
function" from Vite's module runner. Vite 8.3.5 ( vitejs/vite#23775 )
reads a fetched module's code as a string, but Vitest 5.0.5's fs module
cache hands some modules over as a Buffer ( vitest-dev/vitest#11682 ).
It surfaced in the browser tests' server: with SvelteKit 3 it answers a
component test's /media image request, and in CI ( no database ) that
request fails, so SvelteKit asks Vite to source-map the stack.

Pinned exactly so an update doesn't pick 8.3.5 up again. Move Vite back
to latest once a Vitest release carries the fix.
