Add generator front-end: run Wire, parse output into injector graph

Implement the parser and CLI front-end that runs Google Wire and
turns each package's generated wire_gen.go into an injector graph of
creation events, dependency edges, roots, and cleanup functions.

Wire's own build tags and multi-package semantics are reused rather
than reimplemented: Options mirrors wire gen's flags exactly, and
a run resolves multiple packages independently so one failure
doesn't block the others from being reported. wire_gen.go is treated
as transient — generated, parsed, and removed within a run rather
than left behind — so the directory a run leaves is the one it found,
apart from the eventual lifecycle_gen.go output.

The parser is intentionally coupled to the shape Google Wire v0.7.0
emits; testdata fixtures per provider kind (call, value, struct,
fieldsOf) and per failure mode (malformed statements, bad wire.Build
graphs, multi-package layouts) pin that shape so a future Wire
version bump surfaces as a test failure rather than silent drift.

Level computation and lifecycle_gen.go emission remain for later
phases; today's command reports each injector's parsed shape.
