watch mode issues

### tl/dr

`exclude` not works in `sources` for a watch proccess, due "new" `fsnotify`

### Description

I did try to switch to 3.50.0 and immediately notice that bug I tried to solve in https://github.com/go-task/task/pull/2742 

#### Case 1: `exclude` ignored
```yaml
# yaml-language-server: $schema=https://taskfile.dev/schema.json

version: "3"

vars:
  GREETING: Hello, world!

tasks:
  default:
    sources:
      - exclude: ./**/foo/internal/main.txt
      - ./**/main.txt
    method: timestamp
    desc: Print a greeting message
    cmds:
      - task --version
      - which task
      - echo "{{.GREETING}}"
      # - echo $(date) >> ./data/foo/internal/main.txt
      # - echo $(date) >> ./data/qux/internal/main.txt
    silent: true

  init:
    - mkdir -p data/{foo,bar,baz,quux,qux}/internal
    - touch data/{foo,bar,baz,quux,qux}/internal/main.txt

  remove: unlink $(which task)
```

```shell
 > task -fvw --interval=500ms
task: Started watching for tasks: default
task: watching new dir: data/bar/internal
task: watching new dir: data/baz/internal
task: watching new dir: data/foo/internal

task: "default" started
task: [default] task --version
3.50.0
task: [default] which task
3.50.0
task: [default] which task
/opt/homebrew/bin/task
task: [default] echo "Hello, world!"
/opt/homebrew/bin/task
task: [default] echo "Hello, world!"
Hello, world!
task: [default] echo $(date) >> ./data/foo/internal/main.txt
Hello, world!
task: [default] echo $(date) >> ./data/foo/internal/main.txt
task: [default] echo $(date) >> ./data/qux/internal/main.txt
task: [default] echo $(date) >> ./data/qux/internal/main.txt
task: "default" finished
task: task "default" finished running
task: "default" finished
task: task "default" finished running
^C%  
```

so basically every change to excluded pattern triggering task termination and restart.

#### Case 2: some other file changed...

diff to taskfile

```diff
-     - echo $(date) >> ./data/foo/internal/main.txt
-     - echo $(date) >> ./data/qux/internal/main.txt
+      # - echo $(date) >> ./data/foo/internal/main.txt
+      # - echo $(date) >> ./data/qux/internal/main.txt
```

with updated list of watch files change also can be triggered with a new files that are not in watch list.data

## Possible solution, still to check if file is in Allow list, then if it can be rejected rejected.

```yaml
# yaml-language-server: $schema=https://taskfile.dev/schema.json

version: "3"

vars:
  GREETING: Hello, world!

tasks:
  default:
    sources:
      - exclude: ./**/foo/internal/main.txt
      - ./**/main.txt
    method: timestamp
    desc: Print a greeting message
    cmds:
      - task --version
      - which task
      - ./script.sh
    silent: true

  init:
    - mkdir -p data/{foo,bar,baz,quux,qux}/internal
    - touch data/{foo,bar,baz,quux,qux}/internal/main.txt

  remove: unlink $(which task)
```

```shell
# script.sh
#!/usr/bin/env bash

function handle_cerror() {
	EXIT_CODE=$? 
	echo "Handling Error (Cleanup)"
	exit $EXIT_CODE;
}

function handle_ctrlc() {
    echo "Handling Termination"
    exit 1
}

trap handle_cerror ERR
trap handle_ctrlc  SIGINT


echo "Hi! We start Runing" 
sleep 1
echo $(date) > ./data/foo/internal/main.txt 
sleep 1
echo $(date) > ./data/foo/internal/main.data
sleep 1
echo $(date) > ./data/qux/internal/main.txt
sleep 1
echo "We are done!" 
```

```shell
