Update fallback models from GLM-4.6 to GLM-4.7 and
DeepSeek-V3.1-Terminus to MiniMax-M2 across all agent definitions
(aider, claude, llxprt, qwen) in both fish and zsh implementations.

- Heavy (-H/--heavy): Opus only
- Medium (-M/--medium): Sonnet + Subagent
- Light (-l/--light): Haiku

Individual slot overrides unchanged except -H/--haiku → -k/--haiku to
avoid conflict with new -H/--heavy flag.

Aider uses -m for --message and -e for --env-file. synu was using
-m/--model and -e/--editor-model, causing ambiguity.

Now synu only accepts --model and --editor-model (long form) for aider.

Ports the entire synu wrapper to Zsh with equivalent functionality:

- Plugin entry point (synu.plugin.zsh) with standard $0 handling
- Main wrapper function with quota tracking and agent dispatch
- Cache system for model preferences (models.conf format)
- All five agent configurations: claude, opencode, aider, llxprt, qwen
- Interactive model selection using gum
- Shell completions for agents and flags
- Taskfile for testing both shell implementations

Updates documentation to reflect multi-shell support.

llxprt doesn't support setting credentials via environment variables.
Users must run `/key {api_key}` once at the llxprt prompt.

echo $flags concatenates array elements with spaces, causing all flags
to be passed as a single argument. Using printf '%s\n' outputs one flag
per line, which shells properly capture as separate array elements.

Improved the project description to better explain synu's purpose as a
universal wrapper for LLM agents that tracks Synthetic usage and
interactively preconfigures supported agents. Fixed line wrapping and
formatting throughout the document.

- Add aider agent with dual model support (architect + editor)
- Add llxprt agent with openai-compatible config
- Add qwen agent with environment variable config

Agents can now declare which environment variables they set via a
_synu_agent_<name>_env_vars function. The main wrapper automatically
unsets these variables after the agent exits, preventing pollution of
the parent shell environment.

Changes:
- Added _synu_agent_claude_env_vars to declare ANTHROPIC_* and
  CLAUDE_CODE_* vars
- Added cleanup logic in synu.fish to call _env_vars and erase variables
- Fixed string match bug in claude.fish interactive mode (missing --
  separator)
- Updated AGENTS.md to document the new _env_vars function pattern

Some agents (like OpenCode) accept model configuration via CLI flags
instead of environment variables. Added _synu_agent_{agent}_args hook
that returns additional arguments to pass during execution.

Fixed flag extraction loop in main wrapper to handle arbitrary flag
names (including new -m/model for OpenCode). Adds OpenCode agent
definition that uses both cache system and CLI args feature.

Introduces XDG-compliant cache for storing user model preferences across
sessions. Cache is stored in $XDG_CONFIG_HOME/synu/models.conf using
simple key=value format (agent.slot = model_id).

Claude agent now checks cache before falling back to hardcoded defaults,
and interactive mode can save selections. Defaults renamed to "fallback"
to clarify they're only used when no cache entry exists.

Implement a Fish shell utility that wraps AI agents while tracking usage
through the Synthetic API. Features include:

- Universal agent wrapper supporting passthrough execution
- Quota tracking and display for Synthetic API calls
- Claude Code integration with configurable model routing
- Interactive model selection using gum for user-friendly experience
- Shell completions for improved usability
- Agent plugin architecture for extensibility

Initial implementation includes core synu functionality, quota management,
and Claude-specific configuration for routing through Synthetic API tiers.
