fix: add -m/--model and --provider to root hermes parser

[iRonin]

The root hermes parser supports -c/--continue and -r/--resume as shortcuts to launch chat without typing hermes chat. However -m/--model and --provider were only defined on the hermes chat subparser, so combining them didn't work:

hermes -c "my project" -m anthropic/claude-sonnet-4-6
# error: unrecognized arguments: -m anthropic/claude-sonnet-4-6

This adds -m/--model and --provider to the root parser and stops the root→chat passthrough from overwriting them with None.

Now works:

hermes -c "my project" -m anthropic/claude-sonnet-4-6   # resume by name + model
hermes -c -m gpt-4o                                       # most recent + model
hermes -r <session-id> -m anthropic/claude-opus-4-6       # resume by ID + model
hermes -m anthropic/claude-sonnet-4-6                     # new session with model
hermes -c "my project" --provider anthropic              # resume + provider

Thanks for the contribution, @iRonin! This is an automated hermes-sweeper review.

The fix proposed here is already on main — PR #15704 (commit a9fa73a62, merged 2026-04-25) added -m/--model and --provider to the root hermes parser with the same semantics:

• hermes_cli/main.py lines 7391–7409: root-level parser.add_argument('-m', '--model', ...) and parser.add_argument('--provider', ...)
• The kwargs passthrough to cli_main preserves those values and filters out None entries (line ~1188), so they don't overwrite the chat subparser's defaults.

Your PR was on the right track and likely informed the eventual fix. Closing as implemented on main.
