fix: remove useless AST second time parsing

[PhysShell]

Summary by CodeRabbit

• Refactor
  • Optimized internal resource declaration processing by directly constructing abstract syntax trees from JSON facts instead of generating source code and re-parsing.
  • Enhanced resource acquisition and release workflow handling to more accurately track resource subscriptions.
  • Streamlined resource subscription processing by eliminating unnecessary intermediate parsing steps.

📝 Walkthrough

Walkthrough

ownlang/ownir.py replaces the .own source-text generation and re-parse round-trip with direct Module AST construction. It adds _prelude_resources() and a new public to_module() that lowers OwnIR facts into Let/Acquire/Release AST nodes, and updates check_facts() to call check_module() on the resulting AST.

Changes

OwnIR direct AST lowering

Layer / File(s)	Summary
AST node imports and to_module() implementation ownlang/ownir.py	Imports Acquire, FnDecl, Let, Module, Release, ResourceDecl, ResourceMember, Stmt from .ast_nodes; adds _prelude_resources() to build ResourceDecl lists and to_module() to lower each owned-subscription fact into Let(handle, Acquire(Resource)) with optional Release, skipping unresolved-subscription entries; returns the Module plus a handle→fact map.
check_facts() wired to direct AST path ownlang/ownir.py	Imports check_module, calls to_module(facts) to obtain the Module AST, and passes it to check_module(); removes the prior to_own() + _collect() source-generation and parse-failure code path.

Poem

🐇 No more strings to parse and fret,
The AST is built direct!
Acquire, Release, Let in line,
Each resource node is yours and mine.
The rabbit hops the parse-free way—
OwnIR lowered here to stay! 🌿
