Advance the Charon pin from v0.1.73 (dee66030) to v0.1.76 (b360b5d8), continuing the incremental effort to catch the pinned Charon up with upstream (the endgame is dropping scripts/charon-patch.diff entirely). Charon v0.1.74-76 add `TranslateOptions::monomorphize` (kept off; Kani already translates monomorphized instances) and rename the `Locals::vars` field to `locals`. Refresh scripts/charon-patch.diff so its hunks apply against the v0.1.76 sources (context-line drift only; the patch content is unchanged). Co-authored-by: Kiro <kiro-agent@users.noreply.github.com>

🟡 Human review recommended
It updates a pinned upstream dependency and a corresponding patch file, which can have wide compile/runtime impact that should be validated by CI and/or a maintainer.
Pull request overview
This PR advances Kani’s pinned Charon version from v0.1.73 to v0.1.76, updating the few integration touchpoints needed for upstream API/struct changes and refreshing the local Charon patch so it applies cleanly to the new sources.
Changes:
- Bump the pinned
charoncrate version to0.1.76inCargo.lock. - Update the Aeneas LLBC codegen integration for Charon’s
Localsfield rename (vars→locals). - Extend
TranslateOptionsconstruction to include the newmonomorphizeflag (keptfalseas intended) and refreshscripts/charon-patch.difffor v0.1.76.
