Add pass (password-store) entry completion generator

[lucieleblanc]

Summary

Add a Rust generator for the pass (password-store) command so that pass <TAB> lists entries from ~/.password-store (or $PASSWORD_STORE_DIR).

The existing pass.json spec had JavaScript script/postProcess generators inherited from the Fig import, which are ignored by Warp. This PR replaces them with generatorName references to new Rust-based generators.

Changes

New file: command-signatures/src/generators/pass.rs

• entries generator: runs find in the password store directory to list .gpg files, strips the extension via sed, and returns them as "Password entry" suggestions
• directories generator: runs find to list subdirectories, returning them as "Password directory" suggestions for the ls/list subcommand
• Both respect $PASSWORD_STORE_DIR (falling back to $HOME/.password-store)

Modified: command-signatures/src/generators/mod.rs

• Registered the new pass module and generator

Modified: command-signatures/json/pass.json

• Replaced all JavaScript generators objects with generatorName references:
  • Top-level pass, show, edit, cp, mv, rm → "generatorName": "entries"
  • ls/list → "generatorName": "directories"

Testing

All 21 existing tests pass, including all_referenced_generators_exist and all_command_specs_succeed_deserialization which validate that every generatorName in JSON specs maps to a registered Rust generator.

Fixes: warpdotdev/warp#2067

APP-3516 Add pass (password-store) entry completion

pass.json spec exists but has no Rust generator. pass <TAB> should list entries from ~/.password-store directory tree.
