chore: remove binary files

[alexandear]

Summary

Remove committed artifacts.

Why

These artifacts mistakenly committed to the repo in #1164 and #1589.

$ file e2e.test
e2e.test: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=eba9512f03831a33590136029a1260666a1a3423, with debug_info, not stripped
$ file cmd/mcpcurl/mcpcurl
cmd/mcpcurl/mcpcurl: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=7b05c50515653ffa92038aa6db4c399d1c27b5e3, with debug_info, not stripped

What changed

• Remove e2e.test
• Remove cmd/mcpcurl/mcpcurl
• Add e2e.test and mcpcurl to .gitignore

MCP impact

• No tool or API changes
• Tool schema or behavior changed
• New tool added

Prompts tested (tool changes only)

Security / limits

• No security or limits impact
• Auth / permissions considered
• Data exposure, filtering, or token/size limits considered

Tool renaming

• I am renaming tools as part of this PR (e.g. a part of a consolidation effort)
  • I have added the new tool aliases in deprecated_tool_aliases.go
• I am not renaming tools as part of this PR

Note: if you're renaming tools, you must add the tool aliases. For more information on how to do so, please refer to the official docs.

Lint & tests
