add missing `go` keyword to anonymous funcs that
were intended to run as goroutines but were
executing synchronously instead.

* Enhance matcher compilation with caching for regex and DSL expressions to improve performance. Update template parsing to conditionally retain raw templates based on size constraints.
* Implement caching for regex and DSL expressions in extractors and matchers to enhance performance. Introduce a buffer pool in raw requests to reduce memory allocations. Update template cache management for improved efficiency.
* feat: improve concurrency to be bound
* refactor: replace fmt.Sprintf with fmt.Fprintf for improved performance in header handling
* feat: add regex matching tests and benchmarks for performance evaluation
* feat: add prefix check in regex extraction to optimize matching process
* feat: implement regex caching mechanism to enhance performance in extractors and matchers, along with tests and benchmarks for validation
* feat: add unit tests for template execution in the core engine, enhancing test coverage and reliability
* feat: enhance error handling in template execution and improve regex caching logic for better performance
* Implement caching for regex and DSL expressions in the cache package, replacing previous sync.Map usage. Add unit tests for cache functionality, including eviction by capacity and retrieval of cached items. Update extractors and matchers to utilize the new cache system for improved performance and memory efficiency.
* Add tests for SetCapacities in cache package to ensure cache behavior on capacity changes
- Implemented TestSetCapacities_NoRebuildOnZero to verify that setting capacities to zero does not clear existing caches.
- Added TestSetCapacities_BeforeFirstUse to confirm that initial cache settings are respected and not overridden by subsequent capacity changes.
* Refactor matchers and update load test generator to use io package
- Removed maxRegexScanBytes constant from match.go.
- Replaced ioutil with io package in load_test.go for NopCloser usage.
- Restored TestValidate_AllowsInlineMultiline in load_test.go to ensure inline validation functionality.
* Add cancellation support in template execution and enhance test coverage
- Updated executeTemplateWithTargets to respect context cancellation.
- Introduced fakeTargetProvider and slowExecuter for testing.
- Added Test_executeTemplateWithTargets_RespectsCancellation to validate cancellation behavior during template execution.
* fix: segfault in template caching logic
when templates had no executable requests after
option updates.
the cached templates could end up with 0 requests
and no flow execution path, resulting in a nil
engine pointer that was later derefer w/o
validation.
bug seq:
caching template (w/ valid requests) -> get cached
template -> `*ExecutorOptions.Options` copied and
modified (inconsistent) -> requests updated (with
new options -- some may be invalid, and without
recompile) -> template returned w/o validation ->
`compileProtocolRequests` -> `NewTemplateExecuter`
receive empty requests + empty flow = nil engine
-> `*TemplateExecuter.{Compile,Execute}` invoked
on nil engine = panic.
RCA:
1. `*ExecutorOptions.ApplyNewEngineOptions`
overwriting many fields.
2. copy op pointless; create a copy of options and
then immediately replace it with original
pointer.
3. missing executable requests validation after
cached templates is reconstructed with updated
options.
Thus, this affected `--automatic-scan` mode where
tech detection templates often have conditional
requests that may be filtered based on runtime
options.

* Use proxy for dns and ssl templates
- while using template execute level function we need to override custom dialer
* rename overridedialer to customdialer
* Add proxy into hash
- proxy client is shared between non proxy requests
* add dialer into request object
- use request.dialer instead of global variable
* resolve comments
* rename dialer

- add ability to override setDialer function for tcp
- socks proxy is not used incase of tcp protocol
- TCP uses global tcp dialer shared, we need template request level ability to set dialer
This introduces a "nucleitcp" protocol that Nuclei will use when
making MySQL connections as part of its templates.
Previously, this would register (and de-register!) a custom "tcp"
dialer, and that applied globally, so any piece of software that
used a MySQL database and included nuclei in SDK mode would have
its database connections ripped out from under it due to the dialer
hijacking.
By using "nucleitcp" as the protocol, we are free to do whatever
we want with the dialer and not impact any other packages.
Within our `BuildDSN` function, we quietly replace the protocol to
"nucleitcp" if it was "tcp", so nuclei developers don't have to do
anything special to use this functionality; it will always do it.
