ci(clear-signing): unfreeze sync workflow and pin Foundry via setup-foundry

[gvladika]

Which Linear task belongs to this PR?

Ref EXSC-769

Ref (not Fixes) intentionally: this PR delivers the unfreeze plus a reproducibility fix, but defers the ticket's "test-aware guard" scope (see below), so the ticket should not auto-close on merge.

Why did I implement it this way?

The sync bot was frozen in #2172 (schedule + push triggers commented out) to stop it force-pushing sync/lifi-erc7730 off upstream/master and clobbering the hand-authored v2 tests while EF PR #2597 was in flight. #2597 is now merged, so both the regenerated descriptor and the testsv2 file live on master; a fresh bot run branches off a master that already contains that work, and the bot only ever regenerates and commits the descriptor (never the tests file) — so the clobbering risk that motivated the freeze is gone. I verified unfreezing is safe today by diffing the merged master descriptor's clear-signing entries against what this repo generates: all 14 covered test-case selectors render identically (13 byte-identical to our proposal, and swapTokensGeneric is preserved unchanged by the merge since our generator no longer emits it), so EF's snapshot runners stay green on the next sync. While re-enabling the workflow I also fixed a reproducibility bug: both clear-signing workflows installed Foundry by calling foundry-rs/foundry-toolchain directly at an off-pin v1.3.1, bypassing .foundry-version (1.7.1) that every other workflow and the pre-commit hook use — a version skew that could make the verifyClearSigning gate and the sync generate different ABI than a developer regenerating locally; both now use the ./.github/actions/setup-foundry composite action per [CONV:FOUNDRY-SETUP]. The ticket's "make the sync test-aware" scope is deferred because investigation showed EF's notify-missing-tests gate fires only when a descriptor has no testsv2 file at all (ours has one) rather than per new selector — so a new bridge selector does not block the upstream PR, and the only real residual risk is snapshot drift on an already-covered selector, which is a candidate for a follow-up guard rather than a blocker for unfreezing.

Walkthrough

The clear-signing sync workflow now runs on filtered pushes to main and monthly schedules. It separates production and manual concurrency groups. Both clear-signing workflows use the repository-local setup-foundry action.

Changes

Clear-signing workflow automation

Layer / File(s)	Summary
Sync workflow triggers .github/workflows/syncLedgerClearSigning.yml	The workflow enables monthly and filtered push-to-main triggers, retains manual dispatch, and separates production and manual concurrency groups.
Local Foundry setup .github/workflows/syncLedgerClearSigning.yml, .github/workflows/verifyClearSigning.yml	Both workflows use ./.github/actions/setup-foundry instead of the pinned external action.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to abdff

The PR re-enables the sync workflow and standardizes Foundry setup; no actionable merge-blocking risk remains beyond normal checks and review.

In @.github/workflows/syncLedgerClearSigning.yml:
- Around line 19-34: Update the workflow’s concurrency configuration so
scheduled and push-triggered production syncs share one group, preventing
concurrent updates to sync/lifi-erc7730 and duplicate notifications; retain a
separate concurrency group only for manual dry runs if that behavior already
exists. Keep the workflow’s existing idempotent and transparent handling of
generated descriptor and test-file limitations.
