fix(init): generate spinner messages from payload params instead of server detail

[MathurAditya724]

Summary

• Replace server-provided detail spinner messages with CLI-generated messages derived from actual payload params (paths, commands, patches, etc.)
• The server detail string could show misleading file names (e.g. JS config files when running in a Python project). The CLI now always shows truthful info about which files are being read, written, or checked.
• Add describeLocalOp() function covering all 6 operation types: read-files, file-exists-batch, apply-patchset, run-commands, list-dir, create-sentry-project

Examples

Operation	Before (server detail)	After (CLI-generated)
read-files	"Reading next.config.js..."	"Reading settings.py..."
apply-patchset (1 file)	"Applying sentry config..."	"Creating sentry.py..."
apply-patchset (N files)	"Applying changes..."	"Applying 3 file changes (2 created, 1 modified)..."
run-commands	"npm install @sentry/nextjs..."	"Running pip install sentry-sdk..."

Test plan

• Updated 3 existing integration tests to verify server detail is ignored
• Added 12 new unit tests for describeLocalOp covering all operation types and edge cases (empty paths, single/multi file, action breakdowns)
• All 43 tests in wizard-runner.test.ts pass
