LocalAI [bot] 9565db5f94 feat(models): model aliases - redirect a model name to another configured model (#10414)
* feat(config): add model alias field and self-validation

Add ModelConfig.Alias (yaml: alias), IsAlias(), and an alias
short-circuit at the top of Validate() that rejects self-reference and
forbids setting backend/parameters.model on a pure-redirect alias.

* feat(middleware): resolve model aliases and stamp requested/served identity

* feat(modeladmin): reject alias configs with invalid targets on create/edit

Validate alias targets at create/swap entry points (ImportModelEndpoint,
EditYAML, PatchConfig) so a dangling, chained, or disabled alias target is
rejected at save time rather than surfacing as a runtime error.

* feat(api): add GET /api/aliases to list model aliases

Adds an admin-gated read-only endpoint that lists every model alias
config as {name, target} pairs, backed by the loader's existing
GetAllModelsConfigs().

* feat(mcp): add set_alias and list_aliases tools

Expose model-alias management over the LocalAI Assistant MCP surface:
list_aliases (read-only, GET /api/aliases) and set_alias (mutating).
SetAlias is swap-first: PATCH /api/models/config-json/:name swaps an
existing alias's target (validated, non-destructive) and a 404 falls
back to POST /models/import to create a fresh {name, alias} config. The
inproc client mirrors this via ConfigService.PatchConfig + a create path
modeled on ImportModelEndpoint. Deletion reuses delete_model.

* style(mcp): replace em dashes in alias tool comments

* feat(config-meta): expose alias as a model-select field

Add an 'alias' section to DefaultSections() and an 'alias' field override
in DefaultRegistry() so the schema-driven React editor renders the new
top-level ModelConfig.Alias field as a model picker in its own section.

* feat(ui): add alias template card and Manage alias badge

Add an 'Alias / Routing' template to the create-flow gallery that seeds a
minimal name + alias config, and a read-only 'alias -> target' badge on the
Manage Models tab. The capabilities row payload does not carry the alias
field, so the badge resolves targets from GET /api/aliases looked up by name.

* docs(swagger): regenerate for GET /api/aliases

Adds the /api/aliases path and AliasInfo schema generated from the
ListAliasesEndpoint annotation.

* fix: correct alias conversion docs and advertise /api/aliases in instructions

* fix(mcp): write alias config 0600 to satisfy gosec G306

The inproc createAlias path wrote the alias YAML with 0644, which gosec
flags as a new G306 finding on the PR. The LocalAI process is the sole
reader/writer of model configs, so 0600 is correct and keeps the scan clean.
