fix: move file_hash to end of cache key template to prevent prefix matching (#384)

Browse source 
## Summary

Refs #382 (Problem 1).

The default cache key template placed `file_hash` before conditional
segments (`version`, `mise_env`, `install_args_hash`). Because
`@actions/cache` `restoreCache` performs prefix matching on the primary
key, a key without optional trailing segments was always a prefix of a
key with them, causing different workflow configurations to restore each
other's caches unintentionally.

## The bug

Old template:
```
{{cache_key_prefix}}-{{platform}}-{{file_hash}}{{#if version}}-{{version}}{{/if}}{{#if mise_env}}-{{mise_env}}{{/if}}{{#if install_args_hash}}-{{install_args_hash}}{{/if}}
```

Example: Workflow A (no `install_args`) produces key
`mise-v0-linux-x64-<hash>`, which is a prefix of Workflow B's key
`mise-v0-linux-x64-<hash>-<args_hash>`. If only B's cache exists, A
restores it via prefix match.

## The fix

Move `file_hash` to the end of the template so it acts as a terminator:
```
{{cache_key_prefix}}-{{platform}}{{#if version}}-{{version}}{{/if}}{{#if mise_env}}-{{mise_env}}{{/if}}{{#if install_args_hash}}-{{install_args_hash}}{{/if}}-{{file_hash}}
```

Since `file_hash` is always present, no valid cache key can be a prefix
of another.

Also bumps `cache_key_prefix` default from `mise-v0` to `mise-v1` (in
both `src/index.ts` and `action.yml`) to intentionally invalidate
existing caches that may have been saved under incorrect prefix-matched
keys.

## Changes

- `src/index.ts` L43: Reorder `DEFAULT_CACHE_KEY_TEMPLATE` — move
`file_hash` to end
- `src/index.ts` L432: Bump fallback `cache_key_prefix` from `mise-v0`
to `mise-v1`
- `action.yml` L46: Bump default `cache_key_prefix` from `mise-v0` to
`mise-v1`
- Rebuilt `dist/`
