chore: rename merkle-tree -> program-libs, create prover & sdk-libs

[ananas-block]

Repo folder reorg:

1. renamed merkle-tree -> program-libs
   • contains anything that is a separate crate and used in programs
   1. batched -> batched-merkle-tree
   2. concurrent -> concurrent-merkle-tree
   3. moved heap -> program-libs/heap
   4. indexed -> indexed-merkle-tree
   5. moved macros/light -> program-libs/macros
   6. moved macros/aligned-sized -> program-libs/aligned-sized
   7. metadata -> merkle-tree-metadata
   8. moved utils -> program-libs/utils
   9. moved verifier -> program-libs/verifier
2. created sdk-libs folder
   • contains anything that is a rust sdk and intended to be used by devs working with light protocol
   1. moved sdk -> sdk-libs/sdk
   2. light-program-test -> sdk-libs/program-test
   3. client -> sdk-libs/client
   4. macros/light-sdk-macros -> sdk-libs/macros
   5. photon-api -> sdk-libs/photon-api
3. created prover folder
   • contains prover server, circuits, rust client for go prover server
   1. moved light-prover-client -> prover/client
   2. moved light-prover -> prover/server
4. renamed test-programs-> program-tests
   • contains anything that is a test for programs or a crate only used in program tests
   1. moved test-utils -> program-tests/utils
   2. moved merkle-tree/reference -> ./program-tests/merkle-tree

Other Changes:

1. converted all path dependencies to workspace dependencies
2. removed Michal from CODEOWNERS

TODOs for future prs

• remove forester-utils by extracting functionality to forester and sdk-libs/client

Notes

1. consider renaming prover to forester or backend or similar and move forester into this folder as well
2. I tried to remove the crates light-concurrent-merkle-tree, light-indexed-merkle-tree, and light-hash-set, this created version mismatches of bounded-vec and light-hasher in the account compression program and prover/client. We can either fork these crates and move the current versions to program-libs repo or wait to remove these crates until we can remove them from the account-compression program in Q1 or Q2 25.
