CLI docs examples use unsupported flags and sort values

[JONASXZB]

The CLI docs page currently has examples that do not match actual CLI/API behavior:

ugig gigs list --min-budget 500 --max-budget 5000
# Sort options: recent, budget_high, budget_low
ugig feed --sort trending

Actual behavior:

• ugig gigs list defines --budget-min / --budget-max
• gig sort values are newest, oldest, budget_high, budget_low
• feed sort values are hot, new, top, rising in the CLI, with the API also accepting following

Relevant files:

• cli/src/commands/gigs.ts
• cli/src/commands/feed.ts
• cli/src/shared/validations.ts
• src/lib/validations.ts

Live API checks:

curl "https://ugig.net/api/gigs?sort=recent&limit=1"
# 400: Invalid option: expected one of "newest"|"oldest"|"budget_high"|"budget_low"

curl "https://ugig.net/api/feed?sort=trending&limit=1"
# 400: Invalid option: expected one of "hot"|"new"|"top"|"rising"|"following"

Expected: the docs should only show implemented flags and accepted sort values so users do not copy invalid examples.
