Neil 65d28b4dde build(xterm): make the regenerator runnable on Windows and drop dead paths
Readiness review on the restore found one blocking gap and two cheap
cleanups. None of them change the emitted patch, which is byte-identical
before and after.

The generator could not run on Windows at all. Three sites called npm
through execFileSync with shell:false, but npm ships as npm.cmd there,
execFile applies no PATHEXT, and since CVE-2024-27980 it refuses a .cmd
target without a shell. That matters because this harness arms a
blocking gate whose documented remedy is --write, so a Windows
contributor who tripped the gate had no remedy except hand-editing a 7MB
minified bundle, which is the practice the gate exists to abolish. Four
sibling scripts in config/scripts already handle this; the fix follows
them and lands in run(), so the manifest-driven build step is covered
too. git and tar are real executables in System32 and keep resolving
without a shell, which avoids quoting exposure on paths with spaces.

deleteGeneratedSourcemaps was unreachable, since the policy is include.
Deleting it left "delete" as a legal policy value that nothing honoured,
so a manifest asking for it would have silently shipped sourcemaps that
do not match the bundle. The enum is narrowed and an unrecognised policy
now throws rather than falling through.

generatedHunks moved into the test file rather than being dropped; its
partition assertion, that generated and source hunks reconstruct the
whole patch, is worth keeping.

The -text attribute now covers all five patch files. pnpm hashes each of
them byte-for-byte, so the CRLF hazard the xterm patch was protected
from applies equally to node-pty and the three addons. All five were
already LF in the object DB, so this pins existing behaviour. -diff
stays scoped to the xterm patch, since the others are readable.

The doc's claim that the addons reproduce byte for byte is now dated and
marked a one-off measurement rather than an invariant, because nothing
re-runs it.

Effective lines fall from 591 to 568 against the 600 budget. Still the
largest file in config/scripts, and adding a second package to the
manifest would need a split first.
