Subject: [PATCH] ci: pin foundry-toolchain to v1.9.1

Pins foundry-rs/foundry-toolchain to the v1.9.1 commit 908c540300062bd5a7e473851cdb4282204cee09.\n\nWhy now: foundryup became a Rust binary in foundry-rs/foundry#15498, while the v1.7 bootstrap program still invokes it as a bash script. The bootstrap fetches the latest foundryup, so the unpinned action can now break CI.\n\nVerification: workflow and local composite-action files containing foundry-rs/foundry-toolchain were updated; tests not run (workflow ref update only).\n\nRequested by: <@U03C031MDG8> | Quentin Garchery
