Implement persistent transformation triggers

[konard]

Summary

This PR implements issue #3 as optional persistent transformation triggers backed by links storage rather than JSON files.

• Adds PersistentTransformationDecorator to store and apply Once and Always triggers.
• Stores trigger metadata as binary links using the schema Type -> Trigger, Trigger -> Once, Trigger -> Always, Type -> Condition, and Type -> Substitution.
• Supports trigger roots shaped as (Once ((Condition ...) (Substitution ...))) and (Always ((Condition ...) (Substitution ...))).
• Adds CLI options --always, --once, --never, --triggers, --triggers-file, and --embed-triggers.
• Uses a companion <database-name>.triggers.links file by default, while --embed-triggers stores triggers in the main .links database.
• Applies stored triggers after write operations and deletes Once triggers after their first successful application.
• Updates named-link lookup so external schema names can coexist with internal Unicode string storage names.

Test Plan

• dotnet test from csharp/
• dotnet build --configuration Release from csharp/
• bash examples/test_storable_patterns.sh

Resolves #3

[konard]

This function should be implemented in numbered only mode on top of types decorator, and in named mode on top of named decorator that is on top of typed decorator, in any case this feature should be implemented as decorator, that will be able to monitor all create/update/delete/each operations, and if any operations match them in persistent operations, these persistent operations should be applied.

We should have types:

Type -> Trigger
Trigger -> Once
Trigger -> Always
Type -> Condition
Type -> Substituion

With numbers in number only mode, and names in named mode.

So we should have Once and Always triggers with such structure:

(Once ((Condition ...) (Substitution ...)))

or

(Always ((Condition ...) (Substitution ...)))

Once trigger should be itself deleted when triggered. Always trigger just does substitution, if codition matched globally after create/update/delete operations.

As it is decorator it should be optional to use it, so we need some options to make sure our links database file will have persistent transformations enabled.

And yes we should have option to triggers.links file or use triggers directly embeded in the main .links file, that it should be binary links storage file, not json.
