When not using deno.json, ensure latest glue-runtime is used

[Macil]

Follow-up to #30, which applies specifically for Glues that have a deno.json and shows a warning message if an old glue-runtime is being used.

This PR applies to Glues without a deno.json. It causes us to run the user's glue with the right Deno flags to ensure unversioned glue-runtime imports use the latest version.

Greptile Summary

This PR adds --reload=jsr:@streak-glue/runtime to the Deno subprocess flags when the user's glue has no deno.json. Without a lock file to pin a version, Deno may serve a stale cached copy of the runtime; passing --reload for that specific specifier forces a fresh fetch from JSR on every run. The pre-existing deno.json path (outdated-version warning) is preserved and is now reached through the refactored streakRuntimeUpdateChecks helper, which also pre-computes DenoConfigPaths so getOutdatedStreakRuntimeVersion no longer needs to discover config files itself.

Confidence Score: 5/5

This PR is safe to merge; the only finding is a minor API cleanup suggestion (P2).

All logic changes are straightforward and well-reasoned. The --reload flag is scoped precisely to the runtime package specifier, the existing deno.json / warning path is preserved, and the test is updated correctly. The single finding (leaving a dead _filename parameter in the public API) is purely cosmetic and does not affect runtime behaviour.

lib/runtimeVersionCheck.ts — the unused _filename parameter could be removed to clean up the public API.

Important Files Changed

Filename	Overview
commands/dev.ts	Replaces warnIfStreakRuntimeIsOutdated with streakRuntimeUpdateChecks, which now branches on deno.json presence: returns true (triggering --reload) when no deno.json is found, or falls back to the outdated-version warning path when deno.json exists. spawnLocalGlueProcess receives the new boolean and conditionally appends --reload=jsr:@streak-glue/runtime.
lib/runtimeVersionCheck.ts	Refactored to accept a pre-computed DenoConfigPaths instead of a raw filename; filename is now unused (_filename) but kept in the signature. The path import and findDenoConfigPaths call were removed.
lib/runtimeVersionCheck.test.ts	Test updated to call findDenoConfigPaths and pass the result to getOutdatedStreakRuntimeVersion, matching the new signature.

Code Review

This pull request updates the dev command to ensure the latest version of the streak runtime is used by conditionally applying the --reload flag, particularly when a deno.json configuration is missing. The getOutdatedStreakRuntimeVersion function was refactored to accept configuration paths directly. Feedback suggests removing the unused _filename parameter from this function to simplify its signature.

[gemini-code-assist]

The _filename parameter is no longer used within getOutdatedStreakRuntimeVersion because the configuration paths are now passed directly via the denoConfigPaths argument. Removing this unused parameter would simplify the function's signature. Note that call sites in commands/dev.ts and lib/runtimeVersionCheck.test.ts would also need to be updated to reflect this change.
