Fixes #1647.

What changes for users

diff snapshot accepts -i / --interactive, the same flag as snapshot. A baseline saved from snapshot -i can now be diffed without every static line showing up as a change:

agent-browser snapshot -i > before.txt
# ... act on the page ...
agent-browser diff snapshot -i --baseline before.txt

Changes

• cli/src/commands.rs: parse -i / --interactive into "interactive": true; usage strings list it.
• cli/src/native/actions.rs: handle_diff_snapshot passes interactive to SnapshotOptions.
• cli/src/mcp.rs: agent_browser_diff_snapshot takes an interactive boolean and forwards --interactive. Default is false, so existing MCP calls behave as before (note the MCP snapshot tool defaults interactive to true; I left the diff default alone rather than change existing output). The argument building moved into diff_snapshot_command_args, following snapshot_command_args, so it can be tested against the CLI parser.
• packages/@agent-browser/sandbox/mcp-tools.json: regenerated with AGENT_BROWSER_UPDATE_MCP_TOOLS=1.
• --help output and docs/content/docs/diffing.mdx options table document the flag.

Verification

On Linux (WSL2), rustc 1.99:

• cargo fmt -- --check, cargo clippy -- -D warnings: clean.
• cargo test: all pass, including test_diff_snapshot_interactive (both spellings, absent by default) and diff_snapshot_arguments_use_canonical_cli_command (MCP arguments go through the CLI parser and come out with the same interactive, baseline, selector and depth), plus mcp_tool_catalog_snapshot_is_current.
• New e2e e2e_diff_snapshot_interactive_matches_interactive_baseline (headless Chrome, snapshot_diff_probe fixture): a baseline from snapshot -i diffs as changed without the flag and as unchanged with it. cargo test e2e_diff -- --ignored --test-threads=1: all pass.

Not run: the docs site suite. The docs change is one table row.

Companion to #2544 (bare diff snapshot compares against the last snapshot, #1755). The two touch neighbouring lines in handle_diff_snapshot; whichever lands second needs a trivial rebase, which I'm happy to do.
