Task runner (#5)

* simple task-runner

* additional task configurations

* fix shell exec and add shell config

* load env vars

* cleanup and tests

* bug fixes

* Simplify readme

* add http, wait, and template task types

* add condition, group, and git task types

* add command based tasks

* general cleanup

* ignore any ai files

* rename

* add unit tests

* user defined raid subcommands

* command tests

* set task path

* support multi platform

* add zsh support and direct script execution tests

* fix: ensure file is closed after creation in getOrCreateConfigFile

* fix: update getShell tests for Windows compatibility and remove redundant cases

* resolve PR review comments: correctness and cross-platform fixes

* fix: update codecov workflow to include Go setup and improve test coverage command

* fix: add Windows support for getShell function

* fix: enhance command handling and error reporting in task execution

* fix: improve config file handling and error reporting, enhance YAML to JSON conversion

* fix: enhance getShell function to prioritize pwsh over powershell, update tests accordingly

* fix: enhance config file handling by expanding paths and improving directory validation

* fix: validate JSON arrays element-by-element and apply withDefaultDir to Groups

- validateFile now detects top-level JSON arrays and validates each element
  individually, matching extractProfilesFromJSON which supports both single-
  object and array-of-objects profile files
- ForceLoad now applies withDefaultDir to profile.Groups so Shell tasks
  inside Group/Parallel/Retry tasks use the home dir as default working
  directory, consistent with Commands tasks

* test: use exit 0 instead of test -n in literal shell task test

test -n is a POSIX shell built-in unavailable in cmd.exe on Windows,
causing the test to fail in the windows-latest CI matrix.
exit 0 is universally available in both cmd and POSIX shells.

* fix: error on empty YAML in validateFile

An empty YAML file produced zero decode iterations, so validateFile
returned nil even when the schema required fields like 'name'. Track
the document count and return an error when the stream contains no
documents.

* fix: handle -c=path shorthand and -- end-of-flags in applyConfigFlag

Previously applyConfigFlag missed the -c=value shorthand form and would
continue scanning positional args after a -- end-of-flags marker, risking
picking up the wrong config path or treating positional args as flags.

* fix: return error from Write/Set instead of panicking

config.Write() panicked on viper.WriteConfig failure, which crashes
the process instead of letting callers handle the error. Changed Write()
and Set() to return error, and propagated through SetProfile, AddProfile,
AddProfiles, RemoveProfile, and SetEnv.

* fix: discard stdout/stderr during condition command evaluation

A Condition task's Cmd ran with inherited stdout/stderr, polluting
the terminal output with the condition check's output. Condition
evaluation is a boolean probe — its output is noise to the user.

* fix: create parent directories before opening command output file

os.Create fails when the parent directory does not exist. Added
MkdirAll before creating the output file, matching the behaviour
of the HTTP download task. Updated the test to use a path whose
parent is a regular file so MkdirAll itself fails.

* fix: treat non-2xx responses as not-ready in checkHTTP

checkHTTP returned nil for any HTTP response including 4xx/5xx,
causing execWait to consider a server that is returning errors as
ready and stop waiting prematurely.

* fix: add pwsh and ps to shell enum in both schemas

getShell() accepts "pwsh" and "ps" as aliases for PowerShell, but
neither schema listed them, causing schema validation to reject
otherwise-valid configs. Both the root schema and the embedded
runtime copy are updated together.

* fix: validate that Cmd is non-empty in execShell

An empty Cmd would silently invoke the shell with no arguments and
exit 0, masking misconfigurations. Return a clear error instead,
consistent with the required-field checks in HTTP/Wait/Template tasks.

* fix: serialize stdin reads with a mutex in Prompt and Confirm

Both tasks read from os.Stdin and can be marked concurrent:true.
Without synchronization, concurrent Prompt/Confirm tasks interleave
reads, hang, or consume each other's input. A package-level stdinMu
mutex ensures stdin is held exclusively for the duration of each
prompt, making concurrent execution effectively sequential for
user input.

* fix: add stage prefix to Initialize() fatal error messages

Without context, a fatal during initialization only shows the raw
error string with no indication of which stage failed. Adding
"init config:" and "load profile:" prefixes makes CLI failures
easier to diagnose.

* fix: warn to stderr when a profile command shadows a built-in

Commands whose names match reserved subcommands were silently skipped,
giving no indication in help output or logs. Now emits a warning to
stderr so users know why their command is missing.

* fix: nil-check context before dereferencing in Install

Install() accessed context.Profile unconditionally. If called before
Initialize() sets the context, this panics. Added a nil guard
consistent with the pattern used in ExecuteEnv and GetCommands.
