feat: support generic {ide}-remote connection types for space access

Description

Updates the HyperPod CLI to support any {ide}-remote connection type pattern for space access, instead of only allowing the hardcoded vscode-remote and web-ui values. This enables kiro-remote, cursor-remote, windsurf-remote, and any future IDE remote connection types
without requiring CLI changes.

This change aligns the CLI with the server-side operator change in jupyter-k8s-infra#371 (feat: kiro and cursor support), which generalized the WorkspaceConnection validation from
a fixed enum to a regex-based {ide}-remote pattern.

Changes

SDK (hyperpod_space.py)

• Replaced hardcoded {"vscode-remote", "web-ui"} allowlist with regex validation using the same pattern as the operator: ^[a-zA-Z0-9]+(?:-[a-zA-Z0-9]+)*-remote$
• Updated docstring, error message, and usage examples

CLI (space_access.py)

• Updated --connection-type help text to describe the {ide}-remote pattern

Documentation

• README.md — Added kiro-remote and cursor-remote examples to CLI and SDK sections
• doc/cli/space/cli_space.md — Updated parameter table and added example
• doc/getting_started/space.md — Added examples to CLI and SDK tabs
• examples/end_to_end_walkthrough/04-spaces/00-create-space.md — Added section for other IDE connections

Tests

• test_space_access.py — Added CLI tests for kiro-remote and cursor-remote
• test_hyperpod_space.py — Added SDK tests for kiro-remote, cursor-remote, and invalid pattern rejection (6 invalid inputs)

Testing

All space access tests pass (10/10 targeted, 67/67 total space-related tests). No regressions.
