Have verbosity default to level 1 in simulate mode

[ccjmne]

Currently, using stow --simulate <package> would normally only output:

WARNING: in simulation mode so not modifying filesystem.

It is generally meant to be used with --verbose for some more more comprehensive simulation result.

This Pull Request only brings the default verbosity to 1 from the generic 0, but still allows for explicit disabling with --verbosity=0.

Also includes some simple test.

Fixes #82.

Summary by CodeRabbit

• New Features
  • Simulation mode (--simulate) now enables verbose output by default for more detailed logging, unless you explicitly set --verbose=0.
• Tests
  • Added a CLI options test to verify the simulated default verbosity and that an explicit --verbose=0 overrides it.

📝 Walkthrough

Walkthrough

When --simulate is used and --verbose is not explicitly provided, option-processing now sets verbose to 1 before later option sanitization and package checks. A new test verifies the simulated default and that an explicit --verbose=0 overrides it.

Changes

Cohort / File(s)	Summary
Simulation Verbosity Enhancement bin/stow.in	Adjusts merged-options processing to set verbose to 1 when --simulate is present and --verbose was not specified by the user.
CLI Options Test Coverage t/cli_options.t	Adds tests asserting that --simulate without --verbose yields verbose == 1, and that --verbose=0 explicitly overrides the simulated default.

Poem

🐰 In simulation fields I hop and peep,
I raise my voice so secrets don't sleep,
Verbose by default when I pretend,
Yet when you hush me, I'll softly end,
Hooray for clear logs — from a rabbit friend!

Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title accurately and concisely describes the main change: making verbosity default to level 1 when simulate mode is active.
Linked Issues check	✅ Passed	The changes directly address issue #82 by making --simulate imply verbosity level 1 by default, ensuring simulation produces useful output without requiring explicit -v flag.
Out of Scope Changes check	✅ Passed	All changes are within scope: modifications to bin/stow.in implement the default verbosity behavior, and t/cli_options.t adds appropriate test coverage for this feature.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.

In `@t/cli_options.t`:
- Around line 121-138: The top-level Test::More plan still declares "plan tests
=> 6" but you added a new subtest ("simulate defaults verbosity unless
explicitly set") so update the top-level plan to reflect the new total (change
"plan tests => 6" to "plan tests => 7") or switch to no_plan; locate the
existing plan call (the line containing plan tests => 6) and increment it so the
test harness matches the added subtest that uses process_options().
