Migrate all Anchor projects from 0.32.1 to 1.0.0-rc.5 (#548)

* migrate all Anchor projects from 0.32.1 to 1.0.0-rc.5

Rust changes (48 Anchor programs):
- anchor-lang 0.32.1 → 1.0.0-rc.5
- anchor-spl 0.32.1 → 1.0.0-rc.5
- CpiContext::new() program arg: .to_account_info() → .key() (Anchor 1.0 takes Pubkey)
- Context lifetime params: 4 → 2 (transfer-fee project)
- Removed interface-instructions feature (transfer-hook projects)
- Removed [registry] section from all Anchor.toml files

TypeScript changes:
- @coral-xyz/anchor → @anchor-lang/core 1.0.0-rc.5
- TypeScript bumped to ^5.3.3 where needed

Transfer-hook projects (7):
- Added .map_err() wrappers on spl-tlv-account-resolution calls to bridge
  solana-program-error 2.x → 3.x ProgramError type gap
- transmute_pubkey() helper for solana-pubkey 2.x → 3.x in transfer-cost
- Fixed #[instruction] attribute mismatches in transfer-switch (stricter in 1.0)
- AccountInfo → UncheckedAccount in Accounts structs

Compression projects (3):
- Replaced mpl-bubblegum 2.1.1 and spl-account-compression 1.0.0 CPI wrappers
  with raw invoke()/invoke_signed() — these crates depend on Solana 2.x types
  and have no Solana 3.x compatible release yet
- New bubblegum_types.rs in cutils with reimplemented types using borsh 1.x
- Added sha3 crate for keccak256 (solana_program::keccak removed in Solana 3.x)

Why: Anchor 1.0 is the current release candidate. This migration ensures all
program-examples build against the latest framework. Pin to RC until stable.

* ci: trigger workflows on anchor-1.0 branch for testing

* regenerate all pnpm-lock.yaml files for @anchor-lang/core migration

* fix CI: regenerate Cargo.lock, fix borsh try_to_vec, allow clippy diverging_sub_expression

- Regenerated root Cargo.lock to resolve solana-address version conflicts
- basics/rent: replaced try_to_vec() with borsh::to_vec() (borsh 1.x compat)
- clippy: allow diverging_sub_expression (false positive from Anchor 1.0 #[program] macro)

* fix: transfer-cost stack overflow and upgrade SPL crates to Solana 3.x

- Box large InterfaceAccount fields to avoid BPF stack frame overflow
  (12 accounts exceeded 4096-byte limit in Anchor 1.0's try_accounts)
- Upgrade spl-discriminator 0.4.1→0.5.2, spl-tlv-account-resolution 0.9.0→0.11.1,
  spl-transfer-hook-interface 0.9.0→2.1.0 (now compatible with Solana 3.x)
- Remove transmute_pubkey() hack (no longer needed with matching Pubkey types)

+# Anchor 1.0.0-rc.5 Migration Reference
+
+## Proven pattern (from basics/counter/anchor)
+
+### Cargo.toml
+- Change `anchor-lang = "0.32.1"` → `anchor-lang = "1.0.0-rc.5"`
+- Change `anchor-lang = { version = "0.32.1", ... }` → `anchor-lang = { version = "1.0.0-rc.5", ... }`
+- Same for `anchor-spl` if present — change to `1.0.0-rc.5`
+- Add comment: `# Anchor 1.0.0-rc.5 — pin to RC until stable release`
+- **REMOVE `interface-instructions` feature** if present (removed in Anchor 1.0). This affects transfer-hook projects.
+- Keep all other features as-is (`idl-build`, `init-if-needed`, `cpi`, etc.)
+
+### Anchor.toml
+- Remove `[registry]` section if present (no longer used in Anchor 1.0)
+- Keep everything else
+
+### package.json
+- Replace `"@coral-xyz/anchor": "..."` with `"@anchor-lang/core": "1.0.0-rc.5"`
+- Bump `"typescript"` to `"^5.3.3"` if it's on 4.x (required for @solana/web3.js peer dep)
+- Keep everything else
+
+### TypeScript files (tests/*.ts, migrations/*.ts)
+- Replace `import ... from "@coral-xyz/anchor"` → `import ... from "@anchor-lang/core"`
+- Replace `import ... from '@coral-xyz/anchor'` → `import ... from '@anchor-lang/core'`
+- Replace `require("@coral-xyz/anchor")` → `require("@anchor-lang/core")` if any
+
+### Rust source code (lib.rs etc.)
+- Usually NO changes needed
+- If `AccountInfo` is used in an Accounts struct, replace with `UncheckedAccount`
+- If duplicate mutable accounts exist, add `#[account(dup)]` constraint
+
+### Build verification
+- Run `cargo build-sbf` in the anchor project directory to verify Rust builds
+- Run `pnpm install` to verify deps install
+- Do NOT run tests (no validator available)
+
+### interface-instructions removal (transfer-hook projects)
+For projects that had `features = ["interface-instructions"]`:
+- Remove that feature from Cargo.toml
+- The `#[interface]` attribute is removed — check if the program source uses it
+- If it does, this needs manual intervention to refactor
