Check available disk space (cross-platform: wmic/df) before archive
operations to prevent data loss on full disks. Skip archival with
warning if insufficient space (10% safety margin). Clean up partial
archives on tar failure. Proceed with warning when space check fails.

Adds BuildReliabilityService with the following capabilities:
- checkGitIntegrity(): runs git fsck --no-dangling and parses output for corruption
- cleanStaleLockFiles(): removes stale .lock files older than 10 minutes
- validateSubmoduleBackingStores(): validates .git files point to valid backing stores
- recoverCorruptedRepo(): orchestrates fsck, lock cleanup, re-fetch, retry fsck
- cleanReservedFilenames(): removes Windows reserved filenames (con, prn, aux, nul, com1-9, lpt1-9)
- archiveBuildOutput(): creates tar.gz archive of build output
- enforceRetention(): deletes archives older than retention period
- configureGitEnvironment(): sets GIT_TERMINAL_PROMPT=0, http.postBuffer, core.longpaths
Wired into action.yml as opt-in inputs, with pre-build integrity checks and
post-build archival in the main entry point.
Includes 29 unit tests covering success and failure cases for all methods.

Add three optional reliability features for hardening CI pipelines:
- Git corruption detection & recovery (fsck, stale lock cleanup,
submodule backing store validation, auto-recovery)
- Reserved filename cleanup (removes Windows device names that
cause Unity asset importer infinite loops)
- Build output archival with configurable retention policy
All features are opt-in and fail gracefully with warnings only.
