afd4f4c6f9 feat(rfs): flist pack to S3 + read-only route embedding + zinit mount scripts; docs; dev-container tooling 
Summary
- Implemented plain S3-only flist workflow (no web endpoint). rfs pack uploads blobs using write creds; flist route.url is patched to embed read-only S3 credentials so rfs mount reads directly from S3.

Changes
1) New RFS tooling (scripts/rfs/)
   - common.sh:
     - Compute FULL_KERNEL_VERSION from configs (no uname).
     - Load S3 config and construct pack store URI.
     - Build read-only S3 route URL and patch flist (sqlite).
     - Helpers to locate modules/firmware trees and rfs binary.
   - pack-modules.sh:
     - Pack /lib/modules/<FULL_KERNEL_VERSION> to dist/flists/modules-<FULL_KERNEL_VERSION>.fl
     - Patch flist route to s3://READ:READ@host:port/ROUTE_PATH?region=ROUTE_REGION (default /blobs, garage).
     - Optional upload of .fl using MinIO client (mcli/mc).
   - pack-firmware.sh:
     - Source firmware from $PROJECT_ROOT/firmware (fallback to initramfs/lib/firmware).
     - Pack to dist/flists/firmware-<TAG_OR_DATE>.fl (FIRMWARE_TAG or YYYYMMDD).
     - Patch flist route to read-only S3; optional .fl upload via mcli/mc.
   - verify-flist.sh:
     - rfs flist inspect/tree; optional mount test (best effort).
   - patch-stores.sh:
     - Helper to patch stores (kept though not used by default).

2) Dev-container (Dockerfile)
   - Added sqlite and MinIO client package for manifest patching/upload (expect mcli binary at runtime; scripts support both mcli/mc).
   - Retains rustup and musl target for building rfs/zinit/mycelium.

3) Config and examples
   - config/rfs.conf.example:
     - S3_ENDPOINT/S3_REGION/S3_BUCKET/S3_PREFIX
     - S3_ACCESS_KEY/S3_SECRET_KEY (write)
     - READ_ACCESS_KEY/READ_SECRET_KEY (read-only)
     - ROUTE_ENDPOINT (defaults to S3_ENDPOINT), ROUTE_PATH=/blobs, ROUTE_REGION=garage
     - MANIFESTS_SUBPATH, UPLOAD_MANIFESTS (mcli upload optional)
   - config/rfs.conf updated by user with real values (not committed here; example included).
   - config/modules.conf minor tweak (staged).

4) Zinit mount scripts (config/zinit/init/)
   - firmware.sh:
     - Mounts firmware-latest.fl over /usr/lib/firmware using rfs mount (env override FIRMWARE_FLIST supported).
   - modules.sh:
     - Mounts modules-$(uname -r).fl over /lib/modules/$(uname -r) (env override MODULES_FLIST supported).
   - Both skip if target already mounted and respect RFS_BIN env.

5) Documentation
   - docs/rfs-flists.md:
     - End-to-end flow, S3-only route URL patching, mcli upload notes.
   - docs/review-rfs-integration.md:
     - Integration points, build flow, and post-build standalone usage.
   - docs/depmod-behavior.md:
     - depmod reads .modinfo; recommend prebuilt modules.*(.bin); use depmod -A only on mismatch.

6) Utility
   - scripts/functionlist.md synced with current functions.

Behavioral details
- Pack (write):
  s3://S3_ACCESS_KEY:S3_SECRET_KEY@HOST:PORT/S3_BUCKET/S3_PREFIX?region=REGION
- Flist route (read, post-patch):
  s3://READ_ACCESS_KEY:READ_SECRET_KEY@HOST:PORT/ROUTE_PATH?region=ROUTE_REGION
  Defaults: ROUTE_PATH=/blobs, ROUTE_REGION=garage; ROUTE_ENDPOINT derived from S3_ENDPOINT if not set.

Runtime mount examples
- Modules:
  rfs mount -m dist/flists/modules-6.12.44-Zero-OS.fl /lib/modules/6.12.44-Zero-OS
- Firmware:
  rfs mount -m dist/flists/firmware-YYYYMMDD.fl /usr/lib/firmware

Notes
- FUSE policy: If "allow_other" error occurs, enable user_allow_other in /etc/fuse.conf or run mounts as root.
- WEB_ENDPOINT rewrite is disabled by default (set WEB_ENDPOINT=""). Plain S3 route is embedded in flists.
- MinIO client binary in dev-container is mcli; scripts support mcli (preferred) and mc (fallback).

f7c67ee5dd Fix module dependency resolution issues 
- Fix dependency resolution to use built modules from /lib/modules/6.12.44-Zero-OS instead of fresh container
- Fix stage1/stage2 configuration mismatch (only using stage1 modules as intended)
- Fix firmware parsing to ignore comments in modules.conf
- Fix variable binding issues for incremental builds (FULL_KERNEL_VERSION, KERNEL_OUTPUT)
- Module resolution now properly expands 31 → 48 modules with dependencies
- Firmware requirements reduced from 157 bogus → 3 correct packages
- All 48/48 resolved modules validated as available .ko files

b9f94105cf fix: major build system improvements and container output issues 
- Fix container output visibility with proper TTY handling and debug mode
- Fix build order: kernel modules built before initramfs creation
- Implement two-stage kernel build to resolve chicken-and-egg dependency
- Fix sed command issues in kernel configuration with direct execution
- Add diffutils package to container for proper kernel build support
- Enhance NIC module/firmware correlation with intelligent selection
- Fix module staging logic: all NICs loaded in stage1 before network up
- Add smart firmware installation based on module requirements
- Create comprehensive function documentation (scripts/functionlist.md)
- Add debug container script for troubleshooting

Major fixes:
* Container builds now show real-time output
* Kernel builds work with proper GNU diff support
* Module/firmware selection optimized for common hardware
* Build process handles dependencies correctly
* Documentation provides complete function reference
