chore: move setup/dev scripts into scripts/ directory

[GRACENOBLE]

Summary

• Moved setup.sh, setup.ps1, dev.sh, dev.ps1 from the repo root into a new scripts/ directory
• Fixed each script's self-location resolution (SCRIPT_DIR / $ScriptDir) to point one level up to the repo root, since they cd into backend/ and web/ relative to that path
• Updated Makefile's setup and dev targets to call scripts/setup.{sh,ps1} and scripts/dev.{sh,ps1}
• Updated README.md and CONTRIBUTING.md command references and the project structure tree

Test plan

• Verified SCRIPT_DIR resolves to the repo root from scripts/ and correctly finds backend/ and web/
• Grepped repo for any remaining root-level script references — none found outside scripts/ itself

📝 Walkthrough

Walkthrough

Setup and development scripts are referenced from the scripts/ directory across documentation and Makefile targets. The scripts now resolve the repository root before executing existing service startup, dependency installation, environment setup, and migration commands.

Changes

Scripts directory path migration

Layer / File(s)	Summary
Update setup and development command paths CONTRIBUTING.md, Makefile, README.md	Setup and development instructions, Makefile targets, and the documented project tree now use the scripts/ paths.
Resolve script paths from the repository root scripts/dev.ps1, scripts/dev.sh, scripts/setup.ps1, scripts/setup.sh	Shell and PowerShell scripts derive the repository root for their existing relative path operations.

- Line 6: Update the stale root-level command references in scripts/setup.ps1 at
lines 2, 116, and 170 to use .\scripts\setup.ps1 and .\scripts\dev.ps1 as
appropriate. Also update the prerequisite-failure rerun message in
scripts/setup.sh at line 102 to use ./scripts/setup.sh; no other behavior
