Add CEG, TSM feeds

[Siddharth2207]

Motivation

Extend equity feed coverage in rain.pyth by adding CEG and TSM (including pre/post market) mappings so downstream consumers can resolve and read these symbols through the existing Pyth integration.

This PR stacks on #20 (2026-04-19-sgov).

What Changed

• Added new equity feed constants and symbol mappings in src/lib/pyth/LibPyth.sol for:
  • EQUITY.US.CEG/USD
  • EQUITY.US.TSM/USD
  • EQUITY.US.TSM/USD.PRE
  • EQUITY.US.TSM/USD.POST
• Extended getPriceFeedId() resolution for the new symbols.
• Added fork baselines in test/lib/LibFork.sol for CEG and TSM price checks.
• Extended unit tests to validate feed-id resolution, constants, and getPriceNoOlderThan behavior.
• Regenerated pointers/formatting updates required by the parser/pointer workflow.

Validation

• Updated tests in:
  • test/src/lib/pyth/LibPyth.constants.t.sol
  • test/src/lib/pyth/LibPyth.getPriceFeedId.t.sol
  • test/src/lib/pyth/LibPyth.getPriceNoOlderThan.t.sol

Walkthrough

This PR adds support for six new equity price feeds (SGOV/USD, QQQM/USD, VWO/USD, ARKK/USD, CEG/USD, TSM/USD including TSM PRE/POST variants) to LibPyth, refactors deployment configuration by hardcoding MetaBoard address, updates CI workflow with network choices and cleaned environment variables, and applies formatting improvements to function-pointer declarations.

Changes

Equity feeds and deployment updates

Layer / File(s)	Summary
Deployment configuration refactor script/Deploy.sol, .github/workflows/manual-sol-artifacts.yaml, .gitignore	METABOARD_ADDRESS is hardcoded as a constant in Deploy.sol and initialization no longer reads from environment variables. Workflow dispatch input specifies supported networks; repository checkout uses recursive submodules with full history; Nix prelude steps are reordered with rain-pyth-prelude added; deploy environment removes DEPLOY_METABOARD_ADDRESS assignment. .pre-commit-config.yaml is added to .gitignore.
Code formatting cleanups src/abstract/PythExtern.sol, src/abstract/PythSubParser.sol, src/lib/pyth/LibPyth.sol	Function-pointer array type declarations are reformatted for condensed single-line style in PythExtern and PythSubParser; CBBTC/USD constant reformatted to multi-line literal. No logic changes.
New equity price feed constants and routing src/lib/pyth/LibPyth.sol	Constants added for SGOV, QQQM, VWO, ARKK, CEG, and TSM (with TSM PRE/POST variants) defining both Pyth feed IDs and IntOrAString symbol values. getPriceFeedId() extended with else-if branches routing new symbols to their feed IDs.
Test infrastructure and validation for new feeds test/lib/LibFork.sol, test/src/lib/pyth/LibPyth.*.t.sol	Fork block constants for new symbols added to LibFork. Test suites extend coverage with new constant assertions, known-mapping checks, and updated unknown-mapping fuzzing predicates. New external test functions validate getPriceNoOlderThan returns expected price/confidence tuples for each new symbol on Base fork.

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The title mentions only CEG and TSM feeds, but the changeset also adds SGOV, QQQM, VWO, and ARKK equity price feeds alongside other improvements.	Consider revising the title to reflect all newly added feeds (e.g., 'Add equity price feeds: SGOV, QQQM, VWO, ARKK, CEG, TSM') or clarify why only CEG and TSM are highlighted.
