build(fmt): extend make fmt to the Solana preset tree

[shahan-khatchadourian-anchorage]

Summary

Closes #434.

cargo fmt cannot reach any file under chain_parsers/visualsign-solana/src/presets/*/. presets/mod.rs declares its submodules through a generated include:

include!(concat!(env!("OUT_DIR"), "/generated_presets_mod.rs"));

rustfmt does not follow an include! of a path that exists only after codegen, so it formats presets/mod.rs and stops. CI's formatting gate is make -C src generated (which calls make fmt) followed by an "Ensure working tree is clean" check, so the gate inherits the same blind spot and every preset is unchecked.

This PR:

1. Enumerates the preset sources in the fmt target so make fmt -- and therefore the existing CI gate -- covers them. No new CI step.
2. Reformats the 11 preset files the gate never saw.
3. Adds src/rustfmt.toml pinning edition = "2024", so running rustfmt <file> directly on a preset produces the same result as cargo fmt and the Makefile. Bare rustfmt otherwise defaults to edition 2015.

find rather than a literal file list: presets are scaffolded one directory per program and the set grows with each new one, so a hardcoded list silently drops files out of the gate as it goes stale. The recipe echoes the file count (rustfmt 60 Solana preset sources) so a coverage regression is visible in CI logs without dumping 60 paths on one line. The target fails loudly if the directory ever moves.

The find is recursive rather than presets/*/*.rs because three files live one level deeper, under presets/*/tests/.

Files reformatted

drift, exponent_finance, jupiter_borrow, jupiter_earn, jupiter_perps,
kamino_borrow, meteora_damm_v2, meteora_dlmm, neutral_trade,
orca_whirlpool, swig_wallet

Every hunk joins lines that now fit within the width limit -- pure re-wrapping, no tokens change. Largest single change is swig_wallet/mod.rs at -13 net lines.

Test plan

• make -C src generated then git status --porcelain is empty -- reproduces CI's gate exactly and it now passes
• make -C src fmt is idempotent (second run produces no diff)
• All 60 preset files pass rustfmt --check; before this change 11 failed
• make -C src lint -- clippy clean with -D warnings
• cargo test -p visualsign-solana -- passes

Verifying the gate actually bites

Introduce a formatting error in any preset and confirm CI now catches it:

# add a stray blank line to e.g. presets/drift/mod.rs, then:
make -C src generated && git status --porcelain   # non-empty -> gate fails the build

Note

PR #381 is where this surfaced: a struct deletion left a stray double blank line and 17 create_text_field("Raw Data", ...) calls stayed wrapped after their argument got shorter, with CI green throughout. That PR touches only presets/spl_token/mod.rs, which is not in the list above, so there is no conflict with this branch and no ordering requirement between them.

Pull request overview

Extends the workspace formatting gate so Solana preset sources under chain_parsers/visualsign-solana/src/presets/** (which are not reachable via cargo fmt due to an include!(OUT_DIR/...) module pattern) are formatted as part of the existing make -C src fmt / make -C src generated CI flow.

Changes:

• Updates src/Makefile fmt target to find and run rustfmt over all Solana preset .rs sources, and fail if the preset tree can’t be found.
• Adds src/rustfmt.toml to pin edition = "2024" for consistent direct rustfmt behavior.
• Applies rustfmt reflow to the 11 previously-unchecked Solana preset files.
