Local ssb detection (#171)
PSS/SSS detection in the UE code uses a global structure that describe
the cell parameters it is not logical because we will populate this
information from what we read in the MIB and the SIB1 later it also
blocks us to make a cell scanner in a logical manner, just calling pss
detection function with a set of detection parameters and a buffer of
digital radio
this MR fixes this and simplifies the code.

fix(f1): DRB Information has criticality ignore (#173)
See 38.473: this IE is supposed to be "ignore".
Closes: #172

fix(fhi72): add observability to the O-DU (#170)
This change adds printout to packet error/timing counters for the O-DU K
release. In F release these counters are either not present or not
implemented properly.

OAI DFT has scaling issues when the signal is very strong or close to
full scale. So reduce amplitude by 10dB in gnb to prevent
overflow/clipping.

UE DL Channel compensation and LLR optimization (#142)
- Common channel compensation: Extracted nr_channel_compensation() as a
shared function (AVX2/MRC inline) used by both gNB and UE PDSCH/PUSCH
paths, eliminating duplicated compensation logic.
- Common ML/MMSE 2-layer MIMO: Created shared ML LLR and MMSE routines
for 2-layer spatial multiplexing, shared between gNB and UE
demodulation.
- File segregation: Moved common LLR and channel compensation functions
into dedicated source files for better modularity and reuse.
- nr_dlsim -E flag: Added a command-line argument to enable/disable
ML/MMSE equalization at runtime (MMSE default), enabling side-by-side
performance comparison without recompilation.
- Persistent UE buffer allocation: pdsch_dl_ch_estimates, rxdataF_comp,
dl_ch_mag,dl_ch_magb,dl_ch_magr and rho_dl are now allocated once in
PHY_VARS_NR_UE on first use, resize automatically when dimensions
change (resizeAllowed=true), and are freed at UE teardown in
term_nr_ue_signal. Eliminates per-slot heap allocation/free overhead.
- PTRS restricted to one antenna port: PTRS phase tracking is only valid
for a single port; processing now correctly restricted to avoid
unnecessary computation.
- Reduce rxdataF_comp buffer size: MRC combines all Rx antenna
contributions into a per-layer output, so the first dimension was
reduced from Nl * nb_antennas_rx to Nl, reducing buffer footprint
proportionally.
- 256QAM segfault fix: nr_256qam_llr() on gNB side used a VLA for LLRs
without alignment, causing AVX2 load faults. Fixed with
attribute((aligned(32))).

nr_channel_estimation() produces combined output of all antenna ports for each layer. So reduced the buffer size from no. of layer times no. of antennas to no. of layers.

The current state of PTRS will not work for multiple antenna ports because the function assumes rxdataF_comp has signal for all antenna ports but it doesn't as we do MRC after DMRS compensation.

After migration of github, we only use the commit ID for the
pre-ci-check script. This is problematic, because it checks for merges,
excluding the integration branch (expected to have merges), based on the
branch _name_.
In this commit, if a full SHA is detected as the branch "name", use "git
branch --points-at" to get a branch name, then use that to exclude
integration branches (or not). If no branch name is found, the branch
name "" is used, which will trigger the normal merge check (because ""
does not match the integration branch name).

RLC data req: Use API to fill multiple RLC PDUs at gNB (#145)
Use the RLC API to fill a transport block for a given LCID with a single
lock-unlock cycle.
This is a (partial) recommit of 4426fb1 which had been reverted later in
commit 8ed54d7.

ci: remove first-time contributor job in workflow and update Jenkins job badges #147
- Remove the first-time contributor GitHub Actions workflow
- Update Jenkins image builder badge URLs to match the current job
names.
The first-time contributor workflow posts an automated welcome message
through github-actions[bot], creating additional bot activity on pull
requests. Contributor onboarding information is better maintained
through project announcements and documentation, where it is easier to
update and more visible to new contributors.

Migrate the Jenkins dispatch workflow from `pull_request` to
`pull_request_target` so that secrets are available for PRs from forks,
enabling CI to run on external contributions.
- Switch trigger from `pull_request` to `pull_request_target`
- Add `github.event.action` to concurrency group to prevent the `opened`
event from cancelling in-progress CI runs, which caused `detect-changes`
to be skipped on new PRs
- Remap `pull_request_target` back to `pull_request` in the
`X-Github-Event` header for Jenkins compatibility
- Remove `pr-retrigger-ci-instructions`
