## Summary
- Fix false positive cycle detection in `gutil.Dump`
- Change from global pointer tracking to path-based cycle detection
- Shared references (multiple fields pointing to same object) no longer
incorrectly marked as cycles
## Problem
When using `gutil.Dump` with structs containing fields that share the
same `reflect.Type` (e.g., multiple `int` fields), the second field's
type was incorrectly displayed as `<cycle dump 0x...>`.
Example from issue:
```go
type User struct {
Id int `params:"id"`
Name int `params:"name"`
}
fields, _ := gstructs.TagFields(&user, []string{"p", "params"})
gutil.Dump(fields) // Second field's Type shows "<cycle dump>" instead of "int"
```
## Solution
Change cycle detection from global to path-based:
- Add `defer delete()` to remove pointer from tracking set when function
returns
- Only detect true cycles (A→B→A), not shared references (A,B both point
to C)
## Benchmark Comparison
Run benchmark with:
```bash
cd util/gutil && go test -bench=Benchmark_Dump -benchmem -run=^$
```
**Before fix (master branch):**
| Benchmark | ns/op | B/op | allocs/op |
|-----------|-------|------|-----------|
| Shallow | 4071 | 5989 | 85 |
| Nested20 | 105700 | 173993 | 1952 |
| Deep50 | 422515 | 692298 | 4869 |
**After fix (this PR):**
| Benchmark | ns/op | B/op | allocs/op |
|-----------|-------|------|-----------|
| Shallow | 4049 | 5989 | 85 |
| Nested20 | 103065 | 173990 | 1952 |
| Deep50 | 469502 | 692291 | 4869 |
**Performance impact**:
- Memory allocation (B/op and allocs/op) is **identical**
- Execution time is within normal variance (±5-10%)
- The `defer delete()` operation is O(1), negligible compared to
reflection overhead
## Test plan
- [x] All existing `gutil` tests pass (68 tests)
- [x] Added `Test_Dump_Issue2902_SharedPointer` - shared pointer not
marked as cycle
- [x] Added `Test_Dump_Issue2902_SameTypeFields` - original issue
scenario
- [x] Added benchmark tests for performance tracking
- [x] Verified real cycles still detected correctly
Fixes#2902
fix: disable specific staticcheck rules and update lint config
- Disabled staticcheck rules SA1029, SA1019, S1000, and related checks
in `.golangci.yml` to filter out unwanted linter errors.
- Updated staticcheck checks list for more precise linting control.
- Clarified configuration for easier maintenance and future updates.

This pull request standardizes the use of the Go 1.18+ `any` type alias
instead of `interface{}` throughout the codebase. The change improves
code readability and aligns with modern Go best practices. The update
touches many files, including core data structures, code generation
templates, logging utilities, and test data, ensuring consistency across
all usages.
**Type alias migration to `any`:**
* Replaced all instances of `interface{}` with `any` in core data
structures such as `garray` and in generated model structs (e.g.,
`TableUser`, `User1`, `User2`) to modernize type usage.

* Updated function signatures, method parameters, and return types from
`interface{}` to `any` in various parts of the codebase, including code
generation, service logic, and logging utilities (e.g., `mlog`).
