feat(symbolic): add spl-token lemma for inner_test_validate_owner
Adapted from the p-token version (PR #1001). Key differences from the p-token lemma: - spl-token AccountInfo uses raw Aggregate values instead of p-token's PAccountAccount/PAcc wrappers, so the intercept rules extract individual fields (key, is_signer, owner) from AccountInfo using field projections (field 0, 5, 3 respectively) - Case rules match pre-extracted Values directly instead of destructuring PAccount wrappers - Uses _IS_SIGNER wildcard for symbolic bool handling (spl-token's is_signer may be a symbolic BoolVal) - Case 1b handles keys-match + Err(Custom(4)) path via LHS pattern match (avoids booster sort injection errors from requires ==K) - Cases 8-10 (multisig signer-checking) fall through to small-step execution (sufficient for n==1) Also fixes #forceSetLocal -> #setLocalValue in spl-token.md for compatibility with origin/master which removed the redundant helper. Proof result: test_validate_owner_multisig PASSED with 27 nodes in 2886s (vs 123 nodes / 4877s without lemma, 41% speedup). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# SPL-Token lemma rules for `expected_validate_owner_result` and `inner_test_validate_owner`
2+
3+
Adapted from the p-token version (PR #1001). The key difference: spl-token's AccountInfo
4+
uses raw Aggregate values instead of p-token's PAccountAccount/PAcc wrappers. The intercept
5+
rules extract individual fields (key, is_signer, owner) from the AccountInfo, and case rules
6+
match against these pre-extracted Values directly.
7+
8+
Cases 8-10 (multisig initialized signer-checking) are not lemmatized here; they fall through
9+
to small-step symbolic execution. With n==1 this is fast enough.
